The automobile industry has come a long way. Today, car users can lock and unlock their cars without even touching the doors, thanks to the introduction of car transponder keys. A car transponder key has a small chip that emits electronic signals, which are picked up by the car's transceiver, allowing the transponder key to unlock the vehicle. The chip is called a transponder chip and can be found inside the transponder key.
Car transponder keys are primarily designed to allow for remote operation of car doors, but some versions can be used to open the boot of a car or even ignite the engine! Car owners who rely on transponder keys to operate their vehicles can be immensely inconvenienced if their keys stop working. Luckily, transponder key problems are not difficult to detect — even for the average car owner.
Here's a quick troubleshooting guide you should follow when your car transponder key is not working.
Check if your transponder key is getting power supply.
If the transponder key is not getting enough power or is not powered at all, it will not be able to produce and give off signals at the required frequency. Because transponder keys get power supply from a battery, the first thing you should do is to check the battery. If the battery is dead, then a quick solution for the problem would be to replace it with a new battery. You may need to get in touch with your local auto parts dealer to ensure you find the right kind of replacement battery.
Check if your transponder chip is damaged.
If your transponder key still does not work after the battery replacement, it is most likely that your transponder chip was damaged due to one reason or another, and therefore cannot transmit signals to the transceiver. When there's no transmission of signals between the two components, the transponder key will not function. In such situations, the only option may be to purchase a new transponder key from your trusted local dealership or from a local locksmith who specialises in these keys. This may be quite expensive, but keep in mind that you should never take any chances when it comes to the safety of your car. As it is often said, "it's better to be safe than sorry."
Since the new key will come with a different set of programming instructions, you will need to enlist the help of a professional to program the key to your car.Share
