Central Locking
 

Having problems with my key open & close buttons. There is no response at all, but if i use key central lock works as it should work. I have changed battery which didnt help. I had this problem before when occasionally there was no response when i pressed buttons. I have also checked fuses.

- 01 bug eye

could be broken connections on the board in the key you need to inspect it very carefully or it could be whats called a dry joint on the soldering which means the solder has cracked and isnt making contact same result intermittant operation for a while then nothing!
