Transponder Key Problems and Solutions

If you drive a vehicle made in the last two decades or so, then it is highly likely that your vehicle key is actually a type of vehicle key known as a transponder key. Transponder keys have been a mandatory component for all vehicle lock and key systems since the mid-1990s. They ultimately help protect drivers from car theft. Prior to their existence, vehicles were much easier to hotwire and steal. Now, with the presence of a transponder signal system in one’s car, it is nearly impossible for your car to be stolen without the actual key.

How Does a Transponder Key Work?

A transponder key system is actually made up of two separate components. One is the signal that sits inside of your actual vehicle key. The second is the part of the signal that sits inside of your vehicle and is not visible just by looking at your vehicle. These two components work together and communicate through an electronic signal.

In order for one to start their vehicle, both the key part of the transponder system, in addition to the signal within the car, must be clear and free of interference. The two signals recognize each other without drivers even realizing what is happening. This hidden signal actually keeps your car from being stolen. The transponder key itself must be present for the vehicle to start at all. This is why hotwiring and stealing cars that have transponder signals is nearly impossible. Without a signal coming from the transponder key to the car, the car will not start or go anywhere, even if someone were to attempt to hotwire it.

Since the introduction of transponder keys, car thefts have decreased significantly. They are a great invention that takes vehicle safety one step further.

Potential Problems with Transponder Keys

Although transponder keys do a great job at keeping your vehicle secure and within your possession, they are not a foolproof system. Inevitably, just like with any other car part, transponder keys can break or cause other problems for vehicle drivers.

Broken Transponder Key

A broken transponder key could mean a couple of different things. You will know your transponder key is not working properly if it has been smashed or visibly destroyed in some way, but there are also more subtle injuries that can occur inside the key, especially when it comes to transponder keys. The chip inside of your transponder key can become damaged over the course of time due to normal wear and tear. Keys are carried with us everywhere and often abused at the bottom of purses and bags. If your transponder key suddenly stops working, even though there is no visible external damage, it could be that the internal chip has worn out or has been knocked out of place.

Broken Internal Component

It is also possible that the car’s internal transponder signal has become damaged. This will be even more difficult to determine, if not impossible. The car’s internal transponder signal can become damaged in ways similar to your transponder key’s signal. Normal wear and tear over the course of time can cause this to happen or accidents and fender benders may even cause the internal signal to become damaged.

Lost Transponder Key

A lost transponder key will pose a problem for vehicle drivers. This is because not just any spare vehicle key will work if you need to drive your car. Spare keys may not come with a transponder signal and it is unlikely that any spare key for your vehicle will operate the car or open little else than the trunk, doors, and glovebox, if it does not have the signal. If you do happen to lose your transponder key, you will need to have it replaced right away and a new transponder key programmed for you.
