Note: Changing the battery in a wrong manner or using the wrong battery could cause damage to the remote key. Always replace the battery with one that is the same voltage, size and specifications as the original.

If your key fob is submerged in water, you may need to clean the chip before replacing the battery. It's especially important if it was dropped in the sea or soapy water. This must be addressed immediately because exposure to water may damage the chip's electronic circuit and cause the key fob to cease working.

Worn Buttons

The key fob is secured by rubber seals, which will keep water out. The submersion of the keyfob may cause the seals on the keyfob to break and damage the chip's electronic components. This typically happens when you accidentally drop your key fob into the pool or leave it in the rain. If your key fob isn't working after replacing it or reprogramming, the receiver module could be faulty.

Water Damage

This is the part of your seat car keys that receives the signals from the keyfob. It then transmits the signals to the key ignition system. If you have a spare key fob you can test it. This should make the ignition system light come on and the central locking button activate. If this doesn't happen, the receiver module is defective. This is a costly fix, however it can be accomplished by a professional in your local garage.

Radio Interference

The receiver module in your key could cause interference. This can be fixed with the replacement key using a new receiver module purchased from seat key replacement parts.

To replace the battery, pull out the key part and then using your thumb nail or a screwdriver with a flat-headed head, gently push upwards the key fob's compartment cover. Remove the old CR2025 battery and replace it with a brand new battery, making sure that the polarity is in the right place. You can also use a standard-sized key with the transponder chip that was transferred from the worn or damaged key. This can be coded and cut to fit your car in the event that it is needed.

Faulty Receiver Module

The receiver module inside your key fob transmits radio signals to the car. The module could be defective when the fob stops functioning. This can be identified using an OBDII scanner or by reaching out to your dealer.

The remote keyless entry system is vulnerable to interference from other devices that operate on the same frequency. This includes mobile phones, electrical devices, and even household appliances.
