How can I fix the central locking on my Audi A2?

I recently noticed that the central locking on my Audi A2 is not working properly. The key fob sometimes works and sometimes doesn't. What could be the issue and how can I resolve it?

This could be due to a faulty central locking module. I suggest taking your car to a reputable mechanic who has experience working on Audi A2s. They can run a diagnostic test and replace the module if necessary.

Make sure the battery in your key fob is not dead. If it is, replace it with a new one and re-sync the key to your car by following the steps in your owner's manual.
