The missus has decided to learn how to drive so I bought her a cheap Corsa (2001 I think) - anyway, problem I have is that the remote keyfob is buggered. Thought it was just the case but when I took it apart half the components have fallen off and the PCB looks quite rotten.

Is there a cheap option to sort this for her? She's starting to get a bit annoyed by having to use the key all the time :-\
