Why doesn't the immobiliser on my car always read the chipped key?

Question

Why wont the immobiliser on the ignition barrel of my 98 saxo read the key every time?

Answer 1

with our's it was all about which way you put the key in.... think it might have been a wee hicup in citroen's set-up of things!!



on the plus side, it would make your car harder to steal, even if someone did have the key lol!!

Answer 2

My daughter had a problem with the immobiliser on her rover 200. It turned out to be nothing more than a crap battery in the key fob. So with batteries being a lot cheaper than dealers time Id check that first.

It may just be to give your fob a bit of cleaning [not with anything damp obviously] any bit of dirt may cause the signal to be blocked intermittently. Also check around your ignition to make sure it is clear of obstructions.

Failing this it may be possible that the antennae around your ignition has become loose, If any of this does not improve it then get it checked out properly as it will leave you down at some stage

Answer 4

maybe your key fob's faulty? do you have a second? get it checked out at a citroen dealer. it may be that the computer which receives the signal from they keyfob may be faulty. if this is the case, and the situation gets worse, you may not be able to start your car at all! better to be safe than sorry.
