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

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!

Got the key cut at Home Depot. Programmed it myself with a working key. So far it’s working great. I am pleased with the purchase would buy again.

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?

Programming the key was easier than getting the key cut. ACE hardware could not get the grooves deep enough on their manual machine. After 3 attempts I left with a paper weight, per se. Went to local hardware store and they didn't want to do it but I told them it was currently worthless and they couldn't screw it up any worse. They took a shot and it worked and they didn't charge me, so I got the key cut for free. 11 minutes and key was programmed and could manually lock/unlock my 2014 F150 but FOB didn't work. I looked on YouTube and found how to program a fob. You can use any working ket and cycle the Ignition 8 times, can't be too fast or too slow. The door locks will cycle and then you push the lock or unlock button (on the new fob and doesn't matter which button you push) you'll hear the locks cycle then you'll turn the key to the off position and locks will cycle again. Remove the key and try your new key fob and it should work.

This is a story of how I made this key into a key fob by cutting the blade off with a hacksaw.It all started with a claim that this key was guaranteed to program; this proved to be false.The key arrived in no time (shoutout Prime). I took the key to my local hardware store (mistake). They had some issues cutting, but were able to finally cut it. Tried it in my door first (if anyone has dealt with the PATS system, it’s not advisable to try it unless you are actively programming; it will disable your engine). Key worked great in the door so off to home I went.I busted out the laptop and fired up FORScan (extended license v2.4.9 beta), battled the time entry into my PATS system and got to work. I first deleted my current programmed keys to eliminate a previously lost key (I currently have 2 keys but 3 were programmed). While reprogramming, I added the first 2 factory keys with no issues. Put my newly cut key into the ignition and….dun dun dun…it wouldn’t turn the cylinder. TERRIBLE!!! No matter, it was my key now so on to Plan B.I finished the programming cycle and developed my course of action; I decided to swap the circuit board and PATS chip into my factory key. This, in theory, should program as a spare with no issues (if the chip worked as it should have).Completed the swap, attempted to program the spare, nothing; the chip would not program.The best part of the story: I ended up programming the key fob since that’s the reason I wanted a new key anyway. Took a hacksaw and cut the key blade off, colored the silver with a Sharpie, and attached my newly manufactured key fob to the key ring with my factory key.All levity aside, I can’t in good conscience give this product a negative rating as it ended up working for what I wanted it for. However, as another reviewer indicated, the PATS chip may have to be replaced with a more quality product. For the price, it’s worth the risk if you have the capability to conduct PATS programming as a factory key is around $160 (not including dealer programming). Just understand that cutting the key may be an issue and the chip may be junk.Again, worth the gamble for me (roughly 10% of a factory replacement) and it may work for you.

Works great! Easy to have key cut and programmed with ease.
