HQRPBattery Compatible with 3-Series BMW E46 E90 E91 E92 E93 LX8 FZV LX8FZV Key Fob KeyFob 90 Degrees Pins VL2020

Worked for my 2007 335i. Just have to have basic soldering skills and buy a new case, as taking the original one apart breaks it. I have a non comfort access model.

Worked great for bmw e46 key fob. DOES NEED SOLDERING

Only a last century German car engineer would design their key batteries this way, but they did. They also decided it would be a good idea to seal up the key ("This battery has a 20-year life. Who would ever need to replace it?"), so they literally soldered the battery into its little circuit board - I am not making this up. I'm just glad HQRP makes a replacement battery that actually works in this situation. As long as you don't slice open your hand cutting open your key, and as long as you can solder properly - without melting the tiny little circuit board inside your old key - you can bring the key to your 1999 BMW M3 back to life. Which is a good thing, because unless you have a working battery, your key won't work, and you can't start your car, which is not a good thing. This battery, on the other thing, is a very good thing. Well worth the money.

Not a perfect fit for my 2006 E85 3.0si. The prongs line up at a slight angle and one of them was a bit too long, so the keyfob wouldn't close correctly. I had to bend the pin in order to get it to sit flush, and even then it wasn't perfect. It was a 10 minute job start to finish. Most of that time was heating up the key fob with a hair dryer and cutting through the original glue. The soldering itself took less than 2 minutes.However, the battery itself works and I was able to reprogram the key and confirm all functionality. I'll update the review if I have a problem with charging.

Worked perfectly. Make sure that you're decent at soldering components. The most difficult part of the batter replacement was splitting the keyfob apart. These went in well and function properly.

My replacement was fairly easy however 2 days later my remote still doesn’t work. Hoping it needs more driving charging time. It didn’t work before so I didn’t gain or lose anything besides a few bucks and my time.Here’s how I did it.1. Cut key fob apart. Very hard to do. Be careful. Don’t cut deep as there is a circuit board inside.2. Remove old battery by heating up the solder on the opposite side of the battery one at a time. Have tension on the prong side the battery is on so when the solder liquifies on the backside you can pull it through. It happens fast so be ready. Don’t over do it with heat and possibly wreck your board. once you have one side done, move onto the other and remove it and the battery should come out.2. Position your new battery into position under the circuit board so the prongs are lined up with the solder. Once again, heat up the solder while slightly pushing the prong of one side into the solder. As soon as it liquifies the prong will push through quickly. Seat it as far in as possible as it is a tight fit when you try to get your fob put back together. Repeat on the other side.3. Super glue the fob back together. Put a small weight on it while it dries.4. Put key in ignition to charge and go for a ride. I don’t know if it will charge just sitting there in the ignition without the car running.5. Celebrate when you find out it works or hang your head when nothing happens.Good luck. Be careful cutting your Fob open!FYI. I once had my circuit board all the way out of my Fob and tried to use the key without it being inside and my car would not turn over. I reinstalled the circuit board (That had no battery in it) and it started. So…..if you mess up or break your circuit board, you will have a bigger problem.
