It's also one of the most simple problems to fix since it can be replaced in a matter of minutes. To avoid the possibility of a defective coin battery, always make sure you use a new battery that is the same size, voltage and specifications as the first one. Never use a battery exposed to pure water, such as rain, tap-water that is clean, or even soda, because this can damage the internal chip. If the key fob does not work after reprogramming it with an original key, you can go to an authorized dealer.

If not, rolls-royce keys thekeylab.co.uk is most likely due to the 12 volt battery or the receiver module, which needs reprogramming to fix.
Receiver Module Issues
If you've tried a new battery and the remote key fob isn't working, it might be time to replace the receiver module. This is the component that receives the radio frequency signals from the key fob and transforms them into commands for your vehicle's electronic. If the chip in the module is damaged it will not be able communicate with the other modules of the vehicle.
