[PNA]

My battery has died - I installed a Lukas-LK290 (to prevent battery from dropping past 12.4 V) and a dash camera with motion detect feature, and I guess I didn't do it right.

I had left a light on before and the battery couldn't start the car, but this time the battery is so dead that the doors won't open.

What's strange is that the mechanical key doesn't unlock the driver's door!

I can open the trunk, so at least I can get into the car to open the hood and jump it, but I'm wondering if there's any reason why the mechanical key isn't opening the driver's door.

Any ideas would be appreciated.

Also, I'm going to try to get a new (better - automatic version) battery - I have the battery that came with the manual version of the car (small capacity). I heard some success with this, what helps to get it?
