Quick update: Dillon received my remote key today and tested it...said it was obviously a dying battery. Opened the case, replaced battery and resealed (easier said than done), and said it now tests perfectly with a good strong signal. Looking forward to receiving it back.

Great guy, he gave me tips on how he opens them up, if I wanted to attempt it myself...considering I only get one try, I passed. Worth $50 to have it done correctly the first time. Plus, what if it wasn't the battery...then I need to send it off anyway.

Received my key back today from Dillon. Works perfectly and repair is undetectable. I'm very pleased. You can contact him here, he is very responsive and professional. [email protected]

Only if the key blade is not worn out, my only key fob not only had a dead battery, but blade is worn, I had to wiggle the key to open the door each time, so what I end up doing is ordered 2 eBay key fobs, had local locksmith cut the blades and program the 2 new key fobs myself with the AK90+ kit that I also bought from eBay, I also replaced old key bob battery myself, now I have 3 working remote keys.

Dillon has a solution for that.

Joe, where did you order the replacement clear domed roundel buttons for your remotes? Ebay?

I am aware of that...and many are replicas, so one needs to be careful you get oem. But I'm still interested in where Joe obtained his. Thanks

The ones I had before the repair were from eBay and I am pretty sure they were close to OEM. They were a year old and starting to wear though. Dillon included a fresh set so I swapped them out The ones he included are here:

Thanks Joe. I plan to purchase the factory oem ones. The ones Dillon provided do not appear to be oem, but if he is supplying them, I am sure they are durable. (note the diameter does not completely fill the opening. I checked feedback on Amazon and Ebay and with non OEM, folks complain of either poor fit (too small or too large), dome being too flat (making button difficult to depress) as well short life/durability issues. I have the original dome buttons on my 18+ year old key fobs, but the roundels look a bit dark and hazy. I see factory ones being sold by BMW dealers and suppliers for around $8 from Latvia or Lithuania, or $10 domestically.

The inductive toothbrush charger was a "no go" as well. I contacted Dillon today at [email protected]. Super helpful guy, answered all my questions, and showed me photos of his completed work. My biggest fear is if I do it myself, I will hack up the key and it will look like hell when I am done. His work looks professional, so worth the $50 cost to have it done right (he assumes all I need is a battery replacement). I am mailing it off to him tomorrow. Will report back to this thread in a week or two, after I get the key back.
I too used Dillion for my key fob repair. Outstanding guy,great price and great work. If your key isn't working it will be the best $50 you ever spent on your E39.

Just an FYI...if you have a spare remote sitting in the drawer...I would recommend that you bring it into rotation more frequently than every couple of years. I've determined that at every DLS (day light saving) time switch...I also rotate the remote fob. That way each remote gets a good 6 months of constant use.

It also takes approx 30 hours to recharge a deeply discharged remote key...so driving around for a couple of days still isn't enough to recharge a remote's battery that has been sitting in a drawer for a couple of years (unless you're doing a long road trip).

TIP: KL R = ignition position 1

I just bought a 2007 X3 M with problems. I'm afraid I just made it worse. Decided to replace the battery in the only key fob it came with. Before attempting this, the fob would intermittently start the car, but at least would lock/unlock. I found a battery at AutoZone and watched a YouTube video showing how "easy" the process is. Replaced battery on the key fob and got nothing. Tried the original battery and now it no longer does anything. Woops. Stranded.

What steps should I now take to solve this? Is it ruined? Was I supposed to solder something?

I would really appreciate your assistance.

BMWXman, the battery in the remote keys have nothing to do with cranking/starting the engine. These keys do not even need the battery to be present for them to crank/start the engine. I repair the remotes that have no crank problems, but, I hate remotes that have been cut open and dorked up so they cost more to repair. Had one the other day that was so badly damaged it was easier replace the circuit board and most the EWS components over.

I had no idea. I reckon I'm just the latest ignorant BMW rookie here.

Reading the other posts it seemed as if the consensus was that a good battery+undamaged circuit board in fob would mean it would communicate with car's computer and crank. Pretty sure I did not "dork up" the circuit board in fob. Replaced battery but it is not soldered. Car is going into BMW specialist shop tomorrow for bad battery which is causing some other issues. Hoping that this key/fob problem does not confound things. Thanks again.
