How Much Does It Cost To Get A Car Rekeyed?

If you’ve ever found yourself with lost car keys, dealt with a stolen key fob, or purchased a used vehicle and wanted an extra layer of security, the question of how much does it cost to get a car rekeyed likely comes to mind. The process of rekeying your car’s locks and ignition system can vary significantly in price, depending on several critical factors, from the specific make and model of your vehicle to the type of keys it uses and where you choose to have the service performed. This comprehensive guide will break down the costs involved, explain what rekeying entails, and help you understand the variables that influence the final bill.

Understanding Car Rekeying: What Does It Entail?

Before diving into costs, it’s essential to understand what “rekeying” actually means in the context of a car. Rekeying a car is the process of changing the internal tumblers or wafers within your existing lock cylinders (doors, trunk, and ignition) so that only a new, different key will operate them. This is distinct from simply cutting a new key to match the old lock or replacing the entire lock assembly. When your car is rekeyed, the old keys become useless, enhancing security if your previous keys were lost or stolen. The process often involves a skilled locksmith or automotive technician disassembling the lock cylinders, changing the pin configurations, and then cutting new keys to match these updated settings. For modern vehicles, it also frequently involves reprogramming the car’s immobilizer system to recognize the new transponder chip embedded in the key.

Why Would You Need to Get a Car Rekeyed?

There are several compelling reasons why a car owner might consider getting their vehicle rekeyed. The primary motivation is almost always security. Here are the most common scenarios:

Lost or Stolen Keys

This is perhaps the most frequent reason. If your car keys are lost or, worse, stolen, having your car rekeyed is a crucial step to prevent unauthorized access. Anyone who finds or stole your old keys could potentially drive off with your vehicle. Rekeying immediately renders those old keys ineffective, restoring your peace of mind.

Buying a Used Car

When you purchase a used vehicle, especially from a private seller, you can never be entirely sure who else might have copies of the keys. Previous owners, friends, or even mechanics could potentially retain access. Rekeying provides an immediate security upgrade, ensuring that only you and authorized individuals have access to the vehicle. This is a highly recommended security measure for any used car acquisition.

Damaged or Malfunctioning Locks

While rekeying typically addresses key issues, sometimes a lock cylinder itself might be damaged but not entirely broken. If the current key is struggling to turn, or if the lock mechanism is sticky, a rekeying service might include repairing or replacing worn internal components, effectively giving you a refreshed lock system with new keys.

Ignition System Issues

If your ignition cylinder is worn out, jammed, or no longer turning smoothly, a rekeying service often goes hand-in-hand with repairing or replacing the faulty ignition cylinder. This ensures that the entire system functions seamlessly with your new keys.

Security Upgrade

Even without a specific incident, some car owners might simply want to bolster their vehicle’s security. Rekeying can be part of a broader security enhancement strategy, particularly for valuable or classic cars.

How Much Does It Cost To Get A Car Rekeyed? The Average Price Range

The average cost to get a car rekeyed typically falls within a broad range of $150 to $700 or more, depending on the complexity of the job and the factors discussed below. For a basic rekeying of door locks and ignition on an older, simpler vehicle, you might be at the lower end. For newer, high-tech vehicles with complex electronic systems and multiple entry points, the cost can quickly climb. This range includes labor, new key cutting, and often the programming of transponder keys or key fobs. It’s important to get a detailed quote before proceeding, as prices can vary significantly between service providers.

Key Factors Influencing Car Rekeying Costs

Several elements contribute to the final price tag when you need to get a car rekeyed. Understanding these factors will help you anticipate the potential expenses:

1. Vehicle Make, Model, and Year

This is arguably the most significant determinant of cost.
* Older vs. Newer Vehicles: Older cars (pre-1990s) with traditional mechanical keys are generally less expensive to rekey because they lack complex electronic components. Newer vehicles, especially those manufactured after the late 1990s, almost universally use transponder keys, smart keys, or key fobs, which require specialized programming in addition to mechanical rekeying.
* Luxury vs. Economy Brands: Luxury vehicles (e.g., BMW, Mercedes-Benz, Audi, Lexus) often have more sophisticated security systems and proprietary technology, making rekeying more intricate and expensive. Parts and specialized tools for these brands can also be pricier.
* Specific Model Complexity: Some models, regardless of brand, might have unique lock designs or deeply integrated security modules that increase labor time and complexity.

2. Type of Key and Security System

The type of key your car uses directly impacts the rekeying process and cost.
* Traditional Keys: Simple mechanical keys are the cheapest to rekey, as only the physical lock cylinders need to be adjusted and new keys cut.
* Transponder Keys: These keys have a microchip that communicates with the car’s immobilizer system. Rekeying a car with transponder keys requires not only physical rekeying of the locks but also reprogramming the car’s computer to recognize the new transponder chips. This adds significantly to the cost due to specialized equipment and expertise needed.
* Key Fobs/Smart Keys: These advanced systems often involve push-button starts and keyless entry. Rekeying a car with a key fob or smart key is the most expensive option because it involves complex electronic reprogramming of the vehicle’s body control module (BCM) and ignition system, along with the physical rekeying of any remaining manual locks (if applicable). New key fobs themselves are also expensive.

3. Number of Locks to Be Rekeyed

Do you only need the driver’s door rekeyed, or do you need all doors, the trunk, and the ignition cylinder changed? The more lock cylinders that need to be reconfigured, the higher the labor cost will be. In many cases, for security reasons, it’s advisable to rekey all access points to ensure old keys are completely useless.

4. Service Provider: Dealership vs. Locksmith

Where you choose to have the service done significantly impacts the price.
* Automotive Dealerships: Dealerships typically have brand-specific diagnostic tools and parts, making them a reliable option, especially for complex modern vehicles. However, they are almost always the most expensive, often charging premium labor rates and higher prices for parts. They might also insist on full lock replacements rather than just rekeying.
* Independent Automotive Locksmiths: Specialized automotive locksmiths are often more affordable than dealerships. They possess specific tools and expertise for car locks and keys, and many offer mobile services, coming to your location. They are usually more flexible in rekeying existing locks rather than forcing full replacements.
* General Mechanics/Repair Shops: Some general automotive repair shops might offer rekeying services, but their expertise can vary. It’s crucial to ensure they have the right equipment and experience for your specific car’s security system. Prices can be competitive, but always verify their credentials.

5. Location and Emergency Services

Geographic location can affect labor rates, with services in urban areas typically being more expensive than rural ones. Furthermore, if you need emergency rekeying services (e.g., after-hours, weekends, or holidays), you can expect to pay a premium for the convenience and immediate assistance. Mobile locksmith services might also charge a call-out fee.

6. Additional Services and Materials

Beyond the core rekeying, you might incur additional costs:
* New Key Blanks: The cost of the physical key blanks, especially for transponder keys or key fobs, is added to the total.
* Key Cutting: The service includes cutting the new mechanical keys.
* Remote Programming: If your car has keyless entry or a remote start feature integrated into the key fob, programming these functions is an additional step.
* Ignition Cylinder Replacement/Repair: If the ignition cylinder is faulty, it might need repair or replacement, adding to the expense.
* Travel Fees: If a mobile locksmith comes to your location, a travel fee is often applied.

Rekeying vs. Replacing Car Locks: Which Is Better?

Understanding the distinction between rekeying and replacing car locks is crucial for making an informed decision, especially concerning how much does it cost to get a car rekeyed versus a full replacement.

• Rekeying: This involves changing the internal components of your existing lock cylinders so that a new key works, rendering old keys obsolete. It’s generally more cost-effective as it reuses the original hardware. It’s ideal when your locks are physically sound but you need new keys for security reasons (lost/stolen keys, used car purchase). The cost is primarily labor and new key cutting/programming.
• Replacing Locks: This means removing the old lock cylinders entirely and installing brand-new ones. This is necessary if your locks are extensively damaged, rusted, or physically broken beyond repair. Replacing locks can be significantly more expensive than rekeying, as it involves the cost of new hardware for each lock (doors, trunk, ignition) in addition to labor and key programming. In some modern vehicles, replacing the ignition cylinder might also necessitate replacing the entire steering column or other integrated components, driving costs much higher.

For most security-related concerns where the physical locks are intact, rekeying is the preferred and more economical solution. However, if there’s extensive physical damage, replacement might be unavoidable.

The Rekeying Process: What to Expect

When you decide to get your car rekeyed, here’s a general overview of what the process typically involves:

1. Assessment: The locksmith or technician will first assess your vehicle, identify all lock cylinders (doors, trunk, ignition), and determine the type of keys and security system your car uses.
2. Disassembly: The lock cylinders that need rekeying will be carefully removed from the vehicle. This may involve disassembling parts of the door panel or dashboard to access the locks.
3. Internal Component Adjustment: The internal pins or wafers within each lock cylinder are then reconfigured to a new pattern. This effectively “changes” the lock without replacing the entire mechanism.
4. New Key Cutting: Based on the new internal configuration, a new mechanical key (or keys) will be cut to precisely match the rekeyed cylinders.
5. Reassembly: The rekeyed lock cylinders are then reinstalled into your car.
6. Key Programming (for modern vehicles): If your car uses transponder keys or key fobs, the new key’s transponder chip will be programmed to communicate with your car’s immobilizer system. This usually involves connecting specialized diagnostic equipment to your vehicle’s onboard computer (ECU/BCM). If you have a key fob, the remote functions will also be programmed.
7. Testing: Finally, the technician will thoroughly test all the new keys and locks to ensure they function correctly and smoothly.

This process can take anywhere from an hour to several hours, depending on the number of locks, the complexity of your vehicle’s security system, and the experience of the technician.

Tips to Save Money When Getting Your Car Rekeyed

Given the potential cost, here are some strategies to help you save money when you need to get your car rekeyed:

• Shop Around: Get quotes from multiple automotive locksmiths and, if necessary, dealerships. Prices can vary significantly, so comparing estimates is crucial. Do not rush into the first offer.
• Choose an Independent Locksmith: For most rekeying jobs, a reputable independent automotive locksmith will be more cost-effective than a dealership. They often have lower overheads and competitive pricing.
• Consider Mobile Locksmiths: Many automotive locksmiths offer mobile services, coming to your location. While there might be a call-out fee, it can sometimes be cheaper than towing your car to a shop, especially if your car is undriveable due to lost keys.
• Avoid Emergency Services if Possible: If your situation isn’t an absolute emergency, scheduling the service during regular business hours can help you avoid premium rates charged for after-hours or weekend calls.
• Ask About Warranties: Inquire about warranties on both parts and labor. A good warranty can save you money if issues arise shortly after the service.
• Have All Existing Keys Ready: If you have any working keys (even if you’re rekeying due to a security concern), having them available can sometimes streamline the process and reduce labor time for the locksmith, as they might be able to decode existing locks more easily.
• Prioritize What Needs Rekeying: Discuss with the locksmith if you truly need every lock rekeyed. For instance, if your trunk is rarely used and secured separately, you might save a bit by only doing the doors and ignition. However, for maximum security, rekeying all locks is usually recommended.

Importance of Choosing a Reputable Professional

When you’re trying to figure out how much does it cost to get a car rekeyed, the cheapest option isn’t always the best. Choosing a reputable and experienced professional is paramount to ensure the job is done correctly and your vehicle’s security isn’t compromised.

• Verify Credentials: Ensure the locksmith or technician is licensed, insured, and has good reviews or testimonials.
• Specialization: Look for automotive locksmiths who specialize in vehicle security systems. They will have the specific tools and knowledge for various car makes and models.
• Clear Quoting: A professional will provide a detailed, itemized quote upfront, explaining all costs involved, including parts, labor, and any programming fees.
• Avoid Scams: Be wary of unusually low prices or professionals who refuse to provide a detailed quote. Some unscrupulous operators might give a low estimate and then tack on many hidden fees.
