Key lighting up on dash?

Question

my sons citroen saxo has a little symbol of a key that lights up on his dashboard, he recently had an exhaust fitted would this cause a problem in the cat

Answer 1

sounds like your key could be the problem and may need reprograming  

Answer 2

Its a security error message, probably the battery needs to be changed before it looses its code.

Ja.

Answer 3

I doubt that's the problem, it may be a fault with the security system on the Saxo or even something as simple as the key fob needing a new battery (if his car has remote central locking). Most garages have diagnostic systems that will be able to tell you exactly what the problem is & will be able to help you more.

Answer 4

Does the light on the dash go out when the key is inserted in the ignition? If so Its not your key. If not then it's something in the security system

Answer 5

its to do with your alarm/locks, look in your log book
