For car owners, transponder keys provide an extra layer of security that prevents against hotwiring and theft. Specifically, these devices use a microchip to transmit RF signals to your car that allow you to turn on the ignition. But while these modern tools may benefit drivers most of the time, they may also have occasional issues. If your key stops working, here are a few troubleshooting tips.

4 Tips for Transponder Key Troubleshooting

1. Check for Nearby Devices

If you have multiple keys to the same car, they can sometimes interfere with the RF signals that are required to start the engine. When there are two transponder keys in or near your vehicle, it may interrupt the ignition process. As such, you should check the car—and other passengers—to see if another device is nearby. If so, remove it from the vicinity and see if yours works.

2. Replace the Battery

Many transponder keys rely on small batteries to relay messages to the car’s onboard computer system. If you purchased your vehicle used or have had it for several years, there is a chance that the battery may be dead. Usually, these batteries can be purchased at various stores and easily replaced by gently dismantling the device with a screwdriver. For the best instructions, look to your vehicle’s owner manual.

3. Call an Auto Locksmith

When the above tips do not work—or you’ve damaged or lost your car keys—a local auto locksmith can provide the specialized assistance you need. Backed with advanced equipment and automotive expertise, these professionals will be able to reprogram your existing key—or provide, cut and program a new device—to get your car started and keep it secure.

4. Contact Your Auto Dealer

In very rare instances, the problem may not rest with the key—but with the transponder device within the vehicle. When other solutions do not work, it may be necessary to visit your automotive dealer or car repair specialist to have the antenna ring replaced to reestablish proper RF signal communication.
