Keeping Your Transponder Keys Working Efficiently

Transponder car keyHaving your keys locked in your car can be a headache; but what about when you have your keys, but what if the transponder battery for the fob has died? This can actually create the same about of trouble. If you've been locked out of your car or need a remote reprogrammed or replaced, we are more than happy to help. However, here's some tips to avoiding any extra hassle and keeping your keys working properly. 

 

 

Trouble shooting: How to know if you're remote battery is dying.

Since replacing batteries in time is one of the easiest ways to keeping your keys working efficiently, the first step is to know when they'll need a new battery.

  • If you notice that you're remote's signal is losing strength, this may be your first sign. If you have to stand closer to your car to lock it than you used to, or hold it at a certain angle to engage, you know your signal has begun to weaken. 
  • If the light on your key fob does not come on every time you press the button, your battery probably doesn't have much time left. On the majority of remotes, there is a small red light that lights up when the button is pressed to let you know that the signal is being sent. When this light starts coming on only some of the times that you are pushing the buttons, it's time to replace your battery.
  • If it takes multiple clicks to lock or unlock your doors, you know your battery is about to die.

How does a transponder car key work?

A transponder chip is a small chip inside the car key- usually in the handle or fob of the key that works automatically, meaning you don't need to do anything to engage it. However, it does usually require a battery. When you enter your vehicle to operate it, the transponder chip sends a signal to the immobilizer that communicates that the correct key has been used in the car, therefore disarming it. A key missing a transponder chip may fit into the ignition but will not engage the engine unless the signal communicates the match.

What is an immobilizer?

An immobilizer is an electronic security device located inside most automobiles made after approximately 1995. An immobilizer is designed to keep the car from being hot-wired or stolen. Without the correct transponder chip present, an immobilizer will not be disarmed. Your manufacturer can provide more information about how your specific car's immobilizer operates, and this information can usually be found in the car's manual.

Why you should keep replacement batteries on hand:

When a transponder key battery dies, the remote may need to be reprogrammed to communicate with the vehicle. A broken or dead transponder key will often activate an alarm in your vehicle if you locked your vehicle with the signal and then try to unlock or start it manually. In some cases, your transponder key may even need to be replaced. 

If your transponder key does die: key and car

If you do need your transponder key reprogrammed or replaced, we can help with both of those things. And sometimes your vehicle's manufacturer will replace them depending on the kind of warranty you have. Transponder key programming is difficult to do without a professional, so we recommend calling someone as soon as possible.
