Car Key Fob Keyless Entry Remote fits Ford, Lincoln, Mercury, Mazda (CWTWB1U793 3-btn) - Guaranteed to Program

Works perfectly! Took it to the local locksmith and had them program the chip and cut the blade. This one works better than the one I bought from them. The only issue is that sometimes the double tap to unlock passenger doors doesn't always register the first try.

First for the price - this key FOB is a suitable replacement for the factor FOB. But for many people who sent theirs back due to it not working, it may be simply due to poor instructions. I found a couple of big issues. First - there are 2 steps to programming these FOBs in a 2010ish Ford or Lincoln vehicle. You can find them elsewhere in the reviews - but both are critical. The first requires 2 working sets of keys and is commonly documented. This step programs the key so it works in the ignition. BUT - this does not program the actual buttons on the FOB. For that, you have a process that requires you to get in the car, with the door open, press the button to unlock the vehicle. Now put the new key in the ignition and turn it from off to run 8 times quickly (in under 8 seconds), leaving the key in the run position on the 8th cycle. You should hear the locks cycle in the vehicle to tell you it is in program mode. Then on the key fob, press any of the keys to program. If successful, the doors should lock again to acknowledge the programming. At that point, you should be all set.Now here is where I ran into the unexpected... After having the second part of the process fail a couple times, I opened up the FOB and noticed that the battery was installed upside down. The numbers on the battery were facing me. But the design appeared to require the numbers to be down for it to run current through the FOB (it needed to touch both + and - of the battery) I turned it over and the second step of programming worked first try. Seems odd that I would have that issue. But it was definitely a problem. This battery flip coupled with a full set of instructions and it all works perfectly. We'll see how durable it is. It's noticeably lighter than the factory. But seems to be made well enough to last. Thanks to those that posted previously about the 2 sets of steps. That SHOULD be your only challenge. )

Key arrived and looked fine. Had local store cut it. I attempted (several times) to follow the F150 owner's manual procedure to sync the key's chip to the truck's security system. It would not start the truck and I got a security starting error message on the dash. The procedure Ford calls for is to insert an original administrator key, turn to on position and wait 5 secs, remove 1st key, wait about 5 seconds, insert 2nd admin key, turn to on and wait 5 secs, remove key, wait 5 secs, then insert new key and turn to on. If the truck "sees" the new key's chip and is accepted, the door locks cycle.I thought perhaps there was some other trick to programming, so I went to the website listed on the small card that came with the key. That was a joke. It couldn't find instructions for a 2013 Ford F150... a very common vehicle. WTF?I emailed the key manufacturer's customer service address. I got a response later in the evening...I assume during overseas business hours. They gave me two procedures to try. One was described as being a universal process, the other for a different model Ford car. They also said that all keys needed to be in the vehicle since programming the new key would change things such that the other keys wouldn't work. This didn't sound right, and was concerning since I didn't want to mess up my original administrator keys which are needed to program new keys.I went back and forth with customer service and asked a couple times if they could confirm that the Ford procedure should work. They just kept telling me to try the procedure they emailed me.Not sure what to try next, I read through several of the Amazon reviews. It appears there are 2 stages to the programming. I don't know why their customer service didn't know this.First step is to follow the procedure described above to get the key's chip synced to the security system.The 2nd step is to program the remote lock, unlock, start, and panic buttons using a different procedure. That procedure was one of the ones they emailed me. It involves opening the driver's door, pressing the door's unlock button, inserting the new key and cycling from off to on 8 times relatively quickly. I cycled about once per second. The door locks will lock/unlock telling you it is ready to program. I pressed any button on the fob, which apparently tells the vehicle to transfer the program to the key fob, and the locks cycled again. I removed the key and tested the buttons. They seemed to all work. I could lock and remote start the truck. But, as soon as I inserted the key and turned it to "on", the horn would start honking and the dash showed a "starting error".A side note: I placed my original keys far away from the truck when I programmed the fob buttons. My original keys still worked just fine, so their comment about needing to reprogram all keys was not true for my vehicle.From reading on the internet, there was talk about how the transponder chip changed about that time to a new 80-bit chip. The factory keys have an "SA" stamped on the metal part of the key indicating the newer 80-bit chip. I asked customer service if their key had the 80 bit chip and they got back to be saying it did.Customer service didn't know what else to try and asked if I wanted a refund. I contacted Amazon and asked for a replacement.I wanted this to work and since many of the reviews seemed OK, I thought maybe I received a defective key/chip. The replacement key programmed on the first try and everything seems to be work just fine. Hopefully the durability is OK. I wasted a lot of time with their customer service and researching online to get this to work.

Ordered this key for my 2013 f150. Took it to my local locksmith where he cut it and programmed it in about 15 minutes. Everything works great !

I got the key cut had it programmed, but not all the functions work. The lock, unlock and panic features all worked but the remote start simply unlocks the truck (possibly a bad key) I didn’t bother sending it back for a refund because it can open my truck now and start it. I thought about buying another key to see if it might just be a one off. Time will tell.
