Had the ZT-T not been used for a while Martin? I put a new battery on it when I bought the tourer back in 2018.

Sounds like the battery is completely dead. The ticking noise under the bonnet may be the BBUS alarm? The old battery that was on it wasn't holding a charge too well when I bought it and when the battery would run down it would set the alarm off and once that drained it would just be making a sort of loud ticking noise which could be heard from outside the garage I was storing it in at the time.

The driver's door should unlock with the key in the door even with the battery disconnected. Thats how I got into the car when I first bought it as the battery was dead, and quite a few times after when the old battery kept dieing whilst I had the car in storage.

Can't advise whether the tow electrics work though as neither myself or the previous owner had towed anything with it.
