Dead battery - can't open door with mechanical key! - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

PNA · 03-20-2015, 04:30 PM

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?

from my single time experimenting with the physical key, it was difficult to open likely because you cant quite get enough leverage to rotate the darn thing.

I can rotate it - end to end - or at least it feels like it.

did you try the passenger door?

Put more elbow grease into it. The first time can be a little stiff and you'll notice a thump/click when it unlocks.

Sport Tech is the same as the Limited: only the driver's door has the lock.

Well, you were right. It really required a lot of force!

You need an aftermarket battery. The Subaru batteries are crap.

Not this crap again... The stock battery is a Panasonic, it's fine. It's a high compression motor so it needs more power than most, so it's going to show a weak or low charge battery more easily.

The real issue is that these cars draw a lot of current even when sitting off.
I calculated that if the car is left for ~10 days without starting it, the battery will run down.
Add the camera and thats probably more like 5 days. (Just a WAG)

I must have a miracle battery. I went 2 months without a start. Then on 20 degree Fahrenheit day it fired right up. The cranking was slow. But it fired and the battery still lives today.

The BRZ is worse than the FRS because of the keyless entry.

It really is a weak ass battery. Like Stu said, mine sat for two weeks last month and it couldn't start. And the best part is I parked it front first into my garage....

It's totaled.
