e60 Key remote battery? Need some input..
1 Attachment(s)
hello everyone,
Recently i had a dead battery in my 2005 525i. I left the lights on while i was doing some adjusting of the lights and hadnt even thought to turn the car on.
before the car died, the remote worked flawlessly
I jump started the car and now the remote key will barely work for me. I thought first that if it charged in the ignition for awhile it would recahrge and be all set. took the car for a 2 hour drive and its still dead:mad:

my next step is to replace the battery in the remote..?
a few questions..

Is this something i can do myself, or will a trip to the stealer be in my future..? ( new battery and re initialization?)
How much can i expect to spend to get this done if i cannot do it myself.

I have looked up and down and asked on another forum board to get no answers. The manual does not say how to re initialize or replace the battery.

attached is a pic of the key i have.

help! there is nothing more annoying than having full hands and having to set everything down on the ground to put the key in the door and unlock it hahaha

How old is the car battery? That could be the problem since the remote still works ("barely"). I assume you do not have comfort access since you have an 05. Therefore, the battery in the remote is not replaceable without cutting the key open and being very skilled to effect a replacement. Ask me how I know! :(

My first step would be to have the car battery evaluated at AutoZone, Pep Boys?

My dealer changed my key fob battery for 15 bucks.

You must have Comfort Access. The batteries are replaceable in the Comfort Access key fobs.

I do. I didn't realize only CA fobs had replacable batts.

I have a 2004 525i. Same FOB design. What model battery do I need? VL2020, 2320, or 2330? I'm just hoping that someone has opened it up already and measured the diameter of the battery. I just don't want to open mine up just yet before I purchase a battery.
