Exactly what is a transponder key?

In layman’s terms, a transponder key is a manufactured accessory that comes with a car and provides the radio transmission link between the car and the key. It means that a key can be programmed to start one specific, individual car thereby reducing opportunities for theft. Without its transponder key, a car can’t be driven. If you car keys have been stolen read our expert advice on securing your vehicle.

Does every car have an immobiliser?

In most modern cars the transponder chip is incorporated into the top of the car key. Since 1995 it has been a legal requirement for vehicles to be fitted with an immobiliser system for which a transponder key is required. It is in the form of a microchip that contains a serial number that the car manufacturer’s key programmer has made unique to that key. When inserted into the ignition, the key transmits an electronic request to the engine control units (ECU) and the immobiliser box, which then allow the car to start. If the car doesn’t recognize the serial number as the one it was programmed with, it won’t respond to the message and the car won’t start.

The transponder key science bit sounds complicated but at least you know that this wireless, electronic communication between car and key only takes milliseconds yet its failure to operate can cause one expensive headache UNLESS…..you know how to contact The Auto Locksmith.

You don’t need to go back to the dealer, have the car towed anywhere – in fact, you don’t have to worry. One phone call and you can put your mind at rest as The Auto Locksmith will come to you and take care of the rest. We offer car key programming for the majority of vehicles on the road and are often called upon by organisations like The AA, RAC and Green Flag to assist.

If you are buying a car it will include a transponder key so you should ensure that you get at least two keys. Sometimes keys are lost, so having a second validly, programmed transponder key is important. If you buy a car second hand and it only comes with one key, it is recommended that you get a duplicate car key cut. All you have to do is call The Auto Locksmith and we will create a replacement key incorporating a transponder chip that is correctly coded to your car. No time required in having to find a garage– our vehicle locksmith expert comes to you.

Be car security aware

The technology involved in programming keys to specific cars has led many vehicle manufacturers and insurance companies to consider cars with transponder keys to be virtually theft-proof, but they’re not. If you know that your car keys have been stolen, make The Auto Locksmith your second call after the police. Even without having the actual key, The Auto Locksmith can erase the transponder serial numbers logged in your car, ensuring that the thief with your keys won’t be able to steal your car! We can then cut you a replacement car key and program them to your car to ensure a perfect communication between car and key.
