Wie setze ich meinen Schlüsselanhänger zurück, nachdem ich die Batterie ausgetauscht habe?

Car key fobs, also known as electronic car keys, are used to lock and unlock a vehicle's doors and start the engine from a distance. They are convenient, easy to use, and excellent protection against thieves who may attempt to steal your car. However, over time, a malfunction in the car key fob can occur due to a loss of signal, requiring it to be reprogrammed.

When the key fob's battery needs to be replaced, it can be difficult to recall the steps necessary to get it working again. When the battery in your key fob dies, you'll need to reset it. Here's our guide to resetting the key fob after replacing the battery. 

How to reset a key fob after changing the battery?

A Auto owner can do this without needing help from an auto locksmith by following simply the step-by-step procedure below:

Step 1. You should get into the driver's seat and sit with your car key and fob. Ensure all doors are closed, then turn on the ignition by inserting the key in its position to start your engine without starting it yet.

Step 2. Aim your key fob at the transmission receiver in front of your mirror. Press and hold the lock button for a couple of seconds to lock, then press another to unlock doors.

Step 3. Turn off the ignition, then shut down the vehicle as soon as you grab the key. After a few seconds, the car's system will reset the instructions. Press the lock button for a few seconds after turning the ignition and remove the key from the ignition slot.

Step 4. Repeat the process by turning on your car without starting it this time. Press the lock button of the Schlüsselanhänger. You will hear a sound as the car locks itself, which is a sign that the process went successful.

Each car has a unique process for reprogramming or resetting the Schlüsselanhänger. For example, some types of vehicles may require you to press two buttons simultaneously, while other models won't even work unless it's within three feet of the car.

The generic steps I discussed above are common across most models but might not be applicable in all cases. So, carefully read the user manual or search it on the internet before attempting any programming procedures yourself. Different manufacturers might require other steps, as they usually do not provide a universal guide.
