Car Key Fob Keyless Entry Remote fits Ford, Lincoln, Mercury, Mazda (CWTWB1U793 4-btn) - Guaranteed to Program

I only had one original fob for my 2013 Ford Edge, the other was lost, so I had to ask the help of a local locksmith to get this working. Prior to this I did not understand that there are 2 parts to this key: Programming the fob (the buttons) so they unlock/lock the doors, and then syncing the key itself (after it is cut) to the security system of the starter.The locksmith was skeptical that this aftermarket key would work so before cutting they key they tried the fob programming first (on-off 8 times procedure mentioned many times in these reviews). That worked immediately, so they proceeded with the cutting of the key, then they had to bust out a laptop, insert the new key, and let it do its programming thing for 10 minutes. The time delay puzzled me, and my guess is the locksmith's software does some kind of brute-forcing to make the new key work since there isn't a second working key. After waiting a while, all was good to go. Both keys unlock/lock the Ford Edge and start the car just fine. I am glad this inexpensive replacement works. Locksmith was $60 to program for starting, and $20 to cut the key. Apparently anyone can DIY the step to program the fob for unlock/lock so they didn't charge for that.

Delivered quick & as advertised.

Zero stars. Although the product description informs that fob must be programmed by a dealer, the item itself does not comport to Ford proprietary programming software. So, in addition to wasting $19.95 on the item, I paid $79.95 at the dealer only to find it is not compatible with Ford software. Yes, you can cut the key to fit your doors, and it can be programmed to run the peripherals. So if you just want to sit in your car and listen to music with the air on, that’s fine, but if you want to actually drive the vehicle, this product does not have the correct electronic chip to accept the programming. If you still want to try it after reading this, make sure you get it to the dealer within 30 days of purchase or, like me, you won’t even be able to return it.*Buried somewhere in the listing, it does say it will not program if the vehicle has an “ignition guard” but it is my understanding that all newer vehicle have an ignition guard as part of the vehicle protection. My Ford is 13 years old and must have an ignition guard, so how old must a vehicle be to not have it?

After 12 years and 48k miles the "open" button on my Ford Edge car key stopped working. This NEW reasonably priced replacement key was easily programmed by the car's computer and ALL FUNCTIONS work as specified. Also, I thought it was so good that I bought another. Once again, AMAZON saves the day!

works as expected

Very good product. Arrived on time. Key works exceptionally well.

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.

The programing went flawlessThanks for a wonderful product
