It will shout at you.Worse now. I followed a helpful guide by Zagatom in this forum to dismantle and clean up any contacts. One of the wee black square components with lots of legs had a lot of green dirt around which I brushed off. Seems now one of the legs has disintegrated and now it wont lock or unlock or open the boot. It does still start the car. Not sure what will happen if I try to unlock it manually after locked and alarmed by the working key. Will try in the morning.
It needs to be brand new key not a second had eBay jobbie, don't waste you money.OK so it shouts and needs the good key to shut it up. Next bright idea, is it possible to copy the lock unlock signal from the good key on to any other sort of key, and the broken key can still be used to start the engine?
