    I had problems with mine for a few weeks. Would try open the car and it wouldn’t unlock. Then sometimes when going to turn the engine off it wouldn’t work so had to press open on the key fob a few times to turn it off. Car wouldn’t find the key. Boiled down to fob needing a new battery. Tried one battery and no look then put a Duracell in and works with no problems.

    I’ve just had this same problem. Took it to Vauxhall to diagnose turned out to be one of the ariels needed to be replaced.

    Cost me £140, including diagnosing the fault and replacing part

    I'd suspect this 'FRONT INSIDE ANTENNA CIRCUIT OPEN' means the one under the handbrake is faulty. They're not too expensive from Vx.
