Cost of Car Key Replacement
It can be a major hassle to lose your car keys and it can be costly to replace keys. The cost can vary depending on the type of key you have.
The best method to determine the price to replace the car key is to ask a locksmith or dealership. Here is a list that includes several factors that can influence the cost.
Transponder Keys
Transponder keys, sometimes referred to as chip keys, have an electronic microchip that is embedded in the keyhead. The chip sends out an encrypted signal to the car's immobilizer when it is put into the ignition lock cylinder. The code is matched to a unique ID number that is attached to the vehicle. This makes it very difficult to steal a car because it cannot be started without the code.
This type of key was created to make it harder for thieves to wire the vehicle. Transponder keys require an unique code to be activated. They are difficult to duplicate using regular tools, and must be copied only by an auto locksmith.
This means that the transponder key is more expensive than conventional bladed keys. This cost is worth it if you consider the security advantages of this type of key.
If you're considering getting a transponder key, first decide on the importance of security to you. Then consider your budget and lifestyle to determine whether the additional cost is worth it to you.
Dealerships charge a premium to replace car keys. It is because they are the exclusive dealers of certain car models and have large overheads. Fortunately, there are many other car locksmiths that are professional and provide the same service for less money.

If you're not sure if your car has a transponder chip, inquire with your local dealer or auto locksmith. They will be able to tell you whether your vehicle has an electronic transponder and give you an estimate of the cost to purchase a new key. Whichever you choose, less expensive non-transponder keys or the more expensive transponder keys, it is essential to locate a reputable auto locksmith that has expertise working with your particular model of car.
Laser-Cut Keys
Some newer cars use a more advanced key design, known as laser cut keys or sidewinder key. These keys require an auto dealer or locksmith to cut them and then program a computer chip in the key. They are more expensive, yet they offer better security. This is why they're an investment that is more beneficial for those who are looking to protect their car from theft.
Laser-cut keys differ from regular two-sided key because they are only cut in the middle. These cuts are more precise and harder to duplicate than the standard notches on standard key blades. They are also harder to detect, making them an excellent deterrent for would-be thieves.
To make a laser-cut key, the locksmith or dealer utilizes a milling machine that is specifically designed for this purpose. These machines use a bit that looks like drills to slowly strip away the key's metal. They can remove precisely the amount of metal required for a specific key that gives them an extremely high level of accuracy which makes it difficult for a criminal to make their own copy.
Laser-cut keys are more secure than traditional ones because they can't be used to open other vehicles with the same lock. When a regular key is put into the car, it sends a signal that allows the vehicle to recognize it. The engine won't start if the key is not recognized. Laser-cut keys come with a transponder that is associated with a specific vehicle. This means that even if someone thief manages to cut and program a key laser-cut but the engine will refuse to start.
To cut a key laser-cut, a technician will need to have the vehicle Identification Number (VIN) of the vehicle in order to find the right specifications for the CNC machine. This process can last anywhere from 15 minutes up to a few days based on the model and make of the vehicle. After the correct specifications have been completed, a laser-cut key is ready to be programmed by the locksmith or dealer.
Dealerships
Finding a replacement for your car key through the dealership can be the most expensive option but it is often necessary. The positive side is that a lot of times, it is covered by your warranty or insurance. It is best to consult with your insurance company to determine if key replacements are covered under the policy. It's also a good idea to get any damaged keys, stolen or lost deprogrammed by the dealer, as this will prevent anyone from using them in the future.
If you have a standard key fob, getting it replaced by a dealership could be the cheapest alternative. However, if your fob is equipped with a chip and isn't clonable it is likely to cost more money to have it replaced at the dealership or through locksmiths. The cost of a key fob may vary greatly depending on the model and make of your car, therefore it's recommended to talk to local dealerships, locksmiths or mechanics for an accurate price estimate.
You can also save money by having your spare key copied at the dealership. This is cheaper than having it cloned by a locksmith, however you'll want to make sure your spare key is compatible with the vehicle you're using it.
It is essential to note down your VIN whether you're having your car key replaced by a dealer or locksmith. This will ensure that your replacement key is properly fitted and is paired with your vehicle. You can locate your VIN in the owner's manual on your dashboard or in the corner of your windshield or on the front of your engine block.
