key battery - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Owned my car 3 years now...battery will be very weak after 2 months time and will only unlock the trunk after the 2 months have passed. Unlocking the doors is a crap shoot and I must be within a foot of the car to attempt this. After I change the battery, all is well for another 2 months...A pain in the ass yes but the battery is only a couple of bucks and I stock up on them.

The cost of a new key is crazy. Constantly replacing the battery/dealing with it seems to be the way to go.

Where can I get the battery? How much does it usually cost? How exactly do you change the battery? My battery just died on me right now. TIA!

Target, Wal Mart, pretty much anywhere that sells watch batteries. Just pop out your old battery and bring it inside to make sure you get the right model.

My key battery was dead a day after I bought my car. Kinda irked me but spending a few buck for a brand new one wasn't a big deal.

Hi,

The correct Battery is a Lithium CR 2032 3-volt Button Battery. Hope this helps...

Happy Motoring!... Jim'99

Did you have a problem making the key work again after replacing the battery? I replaced my battery already but it still wont work.

Nope, once I replaced the battery the key worked fine. If you replaced the battery correctly it should work, unless you've got some other malfunction in there. Then I'd suggest going to a dealership.

I'm with Toolpants: must be something wrong. I've had my 01 for almost 2 years now. Never needed to change the battery so far. My Lexus key is past 3 years. Honda key is 8 years. No battery changes on any car.

The battery is a standard CR2032, and can be found at just about any drug store or WalMart.
