Goodmans do you still work with sigma alarms? I have one on my VW Golf Cabrio and I have changed the car battery and now the alarm siren is on constantly so I have to leave the battery disconnected! Do you work anywhere near South London? How much would you charge to fix it?

It also happen to my mopar engine parts. This is what I have done...

Disconnect the battery positive lead whilst leaving the key in the ignition for one minute, then reconnecting the lead securely, then removing the key from the ignition and locking the car using the key and leave the car for 2 hours sorted the problem. This problem is a common occurance and is either the fault with the key chip being out of sequence with the immobiliser, or a fault with the recieving ring on the steering lock. If its the key, Renault quoted me £120 + VAT and a 12 day wait for the new key to be delivered from France, then the key has to be re-coded at the Main Dealer. If its the ring, then its between £40 - £60 plus VAT and a 12 day wait for the ring to be delivered from France then It has to be Syncro'd to your key chip and Immobiliser. Point to note though is that I found it worked for me - it may be you have a different problem and it may not work for you, either way - before considering removal of the Battery lead - make sure you have your stereo code!!! Hope you have some luck.
