Fitting a battery isolator switch then locking the car

[Mr Green]

I have a 5 series and the battery is under the back seat, sometimes it doesn't get driven for a few months, on one occasion the battery wouldn't start the car, it was in my garage so it wasn't locked. Now after acquiring a project that is taking up space in the garage I need to park the 5 series on my drive locked(central locking)but want to fit one of these.

If I fit it next to the battery then remove the key I assume the central locking won't lock. If I hold the door button down and close the door it won't have the power to unlock later. My car had a flat battery a few years ago and I had hell of a job unlocking it.
What are my options?

Forget the isolator and get a solar charger from maplins.

This is my project.



So I will need to fit an Isolator switch to this eventually, it hasn't even got a steering lock. Those solar chargers seem like a good idea but I also want to put a carport(for shade) on the drive next year.

No battery, no alarm, no payout if it's stolen? If your insurance company was to know (and care).

Is there a gap in the market?
