Keyless Entry Remote Key Fob Compatible with Ford F150 F250 F350 Escape Expedition Explorer Ranger, Lincoln, Mercury, Mazda and More, Replacement for CWTWB1U331 CWTWB1U345, 3 Button (Pack of 2)

These were virtually identical to the original key fobs and came with an installed CR2032 lithium battery. They were easily programmed to my Ford F150 and work great. Good quality and low price. I recommend it to others.

This was one of the easiest things I've done to a car in quite a while. They just worked. Tested that they were working when I opened the package with a remote tester. All of the buttons put out a signal on both remotes. Went out to my new-to-me 2005 F-250. Got in. Closed the door. Turned the key on and off 8 times, ending on the ignition being on but not running. The locks opened. I hit a button on the first remote. The door unlocked. Hit a button on the second remote. The door unlocked again. Turned off the ignition and checked before I got out of the truck and both remotes worked. Walked away from the truck and they both worked also. Hit the unlock button once to unlock the driver's side door, twice to unlock all doors. Hit the lock button once to just flash the lights when the doors lock. Hit the lock button twice to get the lights to flash and the horn to sound when the doors lock.

Used with 2007 Mercury Mariner. Product seems solid and is good value for the money. Had an issue programming in that I could only get one fob to pair at a time. Each time I programmed the "second" one, the "first" one quit working. Turns out you have to program them both in the SAME key sequence. So turn the ignition on and off 8 times, then when your vehicle locks cycle, push any button on the first remote. Your vehicle will cycle the locks again to confirm. Then hit a button on the SECOND remote and your locks will cycle to confirm the second fob is programmed. It must generate a new code/signal each time you perform the key sequence, so do them all at once.

It is about 70% +/- cheaper than most places. It is also very easy to program. The normal prize to program is about &150.00. I am very impress of the functionality and the price. AWESOME!

Carefully follow the vehicle's owner manual on how to program. Initially I thought the remotes did not work. I checked the batteries. Both showed 3.3V. I tried the programming a third time and it worked! The remotes have good range and are functional. I did not test the panic button.

The fobs were reasonably priced and easy to program.

Easy to program, works like a charm.Not 5 stars because unlike my original, whoseconnecter to the keyring broke,it doesn't offer the chirps that tell meopen or shut. I really liked that I could hear itconfirm the lock from across a parking lot.

Works perfect. After a couple trys. Great quality and value for the price. Auto stores want $50. So glad these were on Amazon! Thanks so much.
