Dead Coin Battery
A dead coin battery is among the most common reasons for the keys for the seat to stop working. The key fob has tiny button cell batteries that is able to keep it powered. Replace it with a new battery that has the same size, voltage, and specifications as the original. If you are replacing the battery, ensure that you remove all metal retaining clips from the back of the key fob. Also, make sure that the contacts are free of corrosion.
If the key fob was exposed to water (such as soapy tap water) it is recommended that you remove and clean the chip with an electronic cleaner or isopropylethanol before installing a brand new battery. The chip may be permanently damaged by moisture. If the key fob still doesn't function after replacing the battery, it might be necessary to replace the key fob.
Faulty Receiver Module
If your key fob was not working after replacing the battery but it didn't function, or stopped working suddenly your receiver module might have experienced a malfunction.

If the keys have been paired, but the receiver module is faulty then you can restart all of the electronics on board by disconnecting the battery with 12 volts for a few minutes. Then reconnect the battery in reverse order (negative cable first and then positive). This will reset the onboard electronic circuit and restore their functionality.
Electronic chip that is malfunctioning
The key fob houses a small electronic chip that sends a signal to the receiver module each time the key is used. If the signal does not match the one the car has stored the immobilizer will be disabled and prevent the vehicle from starting. If the key fob isn't working and you can't reprogram it, it could be due to a malfunctioning chip.
The chip in the key fob is not permanent to the device, and might need to be replaced in order to get it working again. This can be accomplished by removing the key fob from its housing, and then using pins or needles to connect with each metal retaining clip. You'll have to replace them if they are damaged or corrosion-prone. Make sure that any replacement batteries are the same voltage, size and specifications as the original one.
