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

I needed to replace the battery in my "supposedly non serviceable" BMW key fob. After some research on "YouTube University" this battery appeared to be a good choice for a replacement. Upon receiving it, I carefully inspected and compared it to the original battery and it was as I could tell was a good match. Soldered it in place and went through the reprograming procedure and presto! I once again had a fully functional key fob for my car. Perfect.

I purchased this replacement battery for my 2006 Mini Cooper S R53 key fob. My original fob stopped working, and I thought I would have to buy a whole new one. I was so happy to find this battery. Even though I have zero experience with soldering, the installation was surprisingly easy to do on my own. It was a perfect fit, and my key fob works like new again.

soldered this into my key when the dealership said it would take months to get a replacement and they were correct.

I think the battery arrived ok, but it didn't work. I don't know if it was an installation problem, but the battery arrived correctly and the one I ordered.

Doesn't work

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.

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.

My product was awesome thank you.

This was my 2nd order. Received on time. Indispensable for the older BMW remote keys with battery terminals soldered on to the board. [Note: After soldering this new battery on, reset the remote by pressing the 'lock' and 'unlock' buttons together, along with the lock button on the dash. The remote won't work otherwise.]

Few weeks of use started draining after only 1 day without charging.

Genuine product,original part,started working immediately
