Keyless entry problem diagnosis/fix

[jdhx]

Thanks for the comments.  My problem is different in that the key presses always work but the keyless entry hardly ever does.  It is totally random and it makes no difference where the key is at the time.

My current thinking is that the car's sensitivity has dropped just a little which would explain why all three keys fail to work keyless.  I know that when a handle is touched the keys close by do respond with their coded signal effectively saying "I'm here".

The car is booked into a Volvo indy tomorrow, hopefully they will diagnose the issue once and for all.

Thanks
