New Uncut Keyless Entry Remote Control Key Fob Replacement fit for BMW 325 330 318 525 530 540 E38 E39 E46 M5 X3 X5 EWS 315MHZ / 433MHZ

Makes a good spare or everyday use. Nice quality everything worked post programing.

Buyer beware. There was no chip in the key. The remote programmed great but I had to put my own chip in the key.

The media could not be loaded. I ordered the 315 MHz version but when it arrived I was unable to program it to unlock my car. Looking at reviews I see other people might have the same problem but may not be able to diagnose why. I checked the battery and it was 3.3V. I used my SDR to check if it was transmitting. Sure enough it was transmitting, but at 433 MHz, not 315. I was able to switch the frequency of the key’s transmitter using the instructions below:TLDR:If you can’t program it try this:1. Press and hold the unlock button (arrow).2. Press and release the trunk button 5 times.3. Release the unlock button.4. Now try programming in your car.To program the remote to your car:1. Sit in the car with all doors closed.2. Put a functioning key into the ignition.3. Turn the key to the on position and then back off. Some people say you need to do this 5 times.4. Take the key out of the ignition.5. On the new key press and hold the unlock button (arrow).6. Press and release the lock button (BMW logo) 3 times.7. The locks in the car should move and you should now be able to use the remote to lock, unlock, and open your trunk.

A few years back my key remote stopped working for my 02 330ci. A little searching led me to buy a replacement battery, pry open the OEM key and replace the battery and I was back in business. Recently it happened again, but this time, a new battery did not fix it. I recently came across this option and thought it would solve everything, missed the comments saying that the key will not turn on the car. I programmed the remote and it worked easily, using the directions in the comments (push and hold this button, then that button, sit in the car, etc.). THEN, I realized the replacement key would not turn the car on. I figured this was still better than no remote. BUT, started looking for other options and came across a comment that said to start the car with the working key, turn off then immediately use the new key, and guess what, it will start the car. Unfortunately, the next time I tried 30 minutes later, it wouldn't work. Hopefully I'll come across a way to make the new key permanently functional.

its a key and its still not cut or programmed but at least i have a key

Double check the year and make of your BMW. If you have a immobilization chip in your original key. This is NOT the key for you.

Didn't come with a chip inside. My window for return is closed unfortunately.Also doesn't come with no logo like in pictures. Choose a different option don't waist your money.

I'mA: in the US marketandB: have two functional keys with dead remote lock/unlockSo this was perfect for me: all I needed was the 315mHz guts. Popped it open (no glue, thankfully!), took the circuit board out, popped it in to one of my existing key shells with their immobilizer chips, and paired it no problem.As other reviewers and the product page itself have noted, this doesn't have an immobilizer chip, so even if you get it cut and pair the remote, it won't start the car.But, for my specific need to bring a dead remote back to life, it was perfect, pulled apart easily and the electronics worked.
