I lost my only key recently and had to have a key cut by a mobile (and very expensive) auto key specialist. He produced the new key no problem but I noticed that on occasions when I go to start the car I get the message 'Security failed' and I have to try again and all works fine. It seems to happen if I wait for a few seconds for the glow plug light to go out before starting. The remote locking etc works fine. Anyone got any ideas why this is happening?

The only time I have seen "Security Failed" on my X was when I fitted the Message Centre instrument panel and it was expected. After fitting the new IP it had to be programmed into the car using SDD and the keys then had to be reprogrammed. A very 'nervy' 10 minutes.

If it happens again, leave the ignition on and see if the red immobiliser light on the centre console near the handbrake lever begins to flash (It may take a minute to start flashing). If there is an immobiliser error the light should repeatedly flash a two digit code, which may give a clue as to the problem.

Probably the aftermarket transducer not responding properly. It should set a code.
If it makes you feel better, entry level kit to do "all keys lost" on even a few brands/years of cars is really, really expensive.

Thanks Jimbo, the red light does flash as you describe. How do I work out the code?

The light flashes the first digit , then a short pause, then flashes the second digit, then a long pause before repeating. It will continue to do this for several minutes. The possible codes are (I think) somewhere between 11 and 28. You can then look up the meaning of the error code by reading the flowchart that Mark linked to on his last post.

The light just continually flashes, there are no obvious digits or a long pause, even if I leave the ignition on for at least a minute. The only message I get is 'security failed'.
