Keypad for door lock
 

The entry keypad for the door lock on my 06 F350 is starting to work only occasionally.

Has anybody changed one out and/or taken it apart and cleaned contacts or whatever and if so is it a PIA to do or a simple straight forward job?

Thanks in advance for helpful replies

I've used a quality eco-friendly de-greaser with good water pressure. Seems to help mine when it's acting up.
