How Transponder Keys Work
The RFID micro-chip is an anti-theft device that sends a signal to the immobilizer to start the car. Unless the immobilizer recognizes the digital serial number, it won't disengage. So, even if a car thief managed to gain access to the car, they were unable to start it. To work, the programming needs to match the code in the cars' system.
When using the correct key, the chip inside the key disengages the immobilizer to allow the car to start.
Most people ask if they can program chip keys by themselves - but we don't recommend it. It's better to reach out to a professional automotive locksmith to program it for you.
Transponder Keys vs. Non-Transponder Keys
The difference between the two keys pictured below is that one has a micro-chip inside it and the other doesn't. The chip key needs programming before it can start working. But this is not the case with metal keys.
Transponder Key & Non-Transponder (Metal) Key
How to Tell if Your Key is Equipped with a Chip
Most car manufacturers have adopted transponder keys as part of their anti-theft security measures. Yet, older car models might still lack this feature. Figuring out if your car is equipped with a chip key depends on the type of car you have.
Another option is to contact your trusted locksmith service or dealership. Based on the year, make, and model of your vehicle a dealership or auto locksmith can tell if your car takes a chip key or not.
If you currently operate your vehicle with a metal key, then it’s not transponder equipped.
It is not possible to upgrade an older non-transponder vehicle to transponder key. This is because older vehicles are not equipped with built-in immobilizer systems. The opposite holds true as well. Using a non-transponder key when your car is equipped with chip key won't work.
How Much Does It Cost to Replace a Chip Key? Why Is It So Expensive?
The price to replace transponder keys varies based on the year, make, and model of the vehicle. While it’s true that chip keys cost more than metal keys, they also provide more functionality. So, it costs a little more for the added security it offers and the extra work it demands to program it.
Yet, it costs a lot less than the latest replacement car keys like key fobs, smart keys, and remote head keys (RHK). This is also due to the extra functionality smart keys offer that transponders do not.
Where to Get a Transponder Key Made
Maybe you lost the only key to your car or it is broken. Where do you go for chip key replacement service?
We suggest you go to a reputable professional locksmith company to save money. A dealership can also duplicate car keys with chips. But a mobile locksmith can do it much cheaper than dealerships. A mobile locksmith will also save you the hassle and money of getting your car towed.
Go with a local locksmith for hassle free transponder key replacement service. However, not all locksmiths are equal. There are fraudulent locksmiths who lurk around to take advantage of unsuspecting customers. So, make sure you're dealing with a trustworthy car locksmith that has been around for a while.
If you lost your keys a locksmith technician can delete your old key codes from your car computer. This will prevent the old keys from operating your car.
