There was mention of a battery?
I'm locking it with the key now....

The alarm module has an internal rechargeable battery, but they don't last forever. Some have managed to take the module apart and replace the battery. It can also be corrosion in the circuit board. The main 12v battery beginning to weaken can also cause alarm issues. It can be many things. In the end I took my V70 to a main dealer and they diagnosed the problem being a door switch.
