Review on 🔑 Keyecu EWS Modified Flip Remote Key: 4 Button for BMW X5 Z3 Z4 2001-2005 HU92 Blade - Enhanced Security & Functionality by Victor Ahmed

There were problems programming the remote functions. Follow the instructions provided. Writes: insert the key and turn the ignition to position 1, then pull it out for 5 seconds, then press and hold the unlock button, then press the lock button three times. Didn't work with the new remote control. I accidentally pressed the lock/center button 4 times instead of 3 while holding the unlock and it programmed the new Keyecu. If your old remote control loses its function, repeat the programming for both remote controls. Insert the key and turn it to position 1, then remove the key. Unlock the old remote, press the latch 3 times, release both buttons (the door lock will switch), then unlock the new Keyecu remote and press the latch 4 times. (Door lock unlocks again) Must do both quickly.
