key battery

  1. E46 (1999 - 2006)
    I bought an E46 with batteries dead in all 3 keys and within few days before I had time to replace the key batteries my door lock cylinder broke and I can't get into the car. Now replacing the key batteries won't help me because I can't pair them with the car, right? I have found this video...

    My car prompted me to replace the battery in my key fob. I'm complied with the order. I'm confident that the battery is installed correctly. The battery is new from Lowes. Nonetheless, I'm still getting the error message. So I tried using my husband's key fob. I get the same message. This is...

    I'm brand new so forgive me if this is a stupid question. Just bought an old BMW second hand (325i 2003). I drove it home yesterday and it was fine. The stereo and power locks wouldn't work so I replaced the fuses. Success both worked, but after getting out of the car with doors locked, the key...

    My key remote stopped working and I opened it up to try to replace the battery. The problem is I can’t remove the old battery using a razor or small pliers. The battery is soldered to the electronic board. How do I remove the old battery?

    Hey folks, just as an FYI. When it comes time to replace your key fob battery it takes a CR2450. Just pull out the mechanical key and the back panel pops out quite easily using the tabs. I just slid a toothpick under the left side (looking at the back panel with the "fat" end near you) until...

    Short version: My 2011 535i recently went out of warranty. Car warns us to change the remote control battery whenever my wife's key is in range of the car. We buy a new battery at a battery store and I install it. Car still giving the warning. I checked the battery output just to see if the...

    I have this 2007 335i (with comfort access) since 2009 and I was using the same key since then. For about 6 months ago, I have experenced that the batteries start dying quicker and quicker.

    Hi all, First time poster here! I've read some of the other forums on similar problems but haven't been able to find the answer. I got a new new fob for my 2008 BMW 320d coupe m-sport.

    Hi, I was driving my 550 and pressing the gas down to see the speed. As my speed was increasing, nothing crazy, I think 105-110 a symbol popped up stating "LIMIT". The symbol popped up near my dials. Does anyone know what this means? Also, I have key less entry and all that go stuff. I don't...

    YES, I have looked at the WIKI and YES there are answers in there! BUT I do have some questions! Ok, the first thing that is irritating me is on of the keys doesn't quite work. I mean, it works but intermittently and only really close to the car. And not always. I have read two schools of...
