Title: Worked great on 2014 Ford Edge SEL
Review: This worked perfectly. I would have had to pay $600 to have a locksmith replace 2 keys/remotes instead of this fantastic deal kit.Now, the fun stuff. To program the car to accept a transponder (the chip in the key that enables you to start the car), you can do it two ways– one is to use the typical end-user instructions that requires two working keys to program a 3rd, or the other is to use an OBD tool and special software to make programming changes to the car directly.I only had one working key– but I also had a second plastic housing from another key which had broken off– which means I had a second transponder chip but no second key. My car still trusted the transponder from the broken key. Here’s what I did:1. I used painters tape on the good key and cut the tape with a razor to match. I then peeled the tape off and placed it on one of the blank keys from this kit. I then used a dremmel and some tiny precision files, and a digital caliper to confirm measurements to clone the shape from the tape onto the key blank. I now had a second key with an unrecognized transponder. I verified I could open the door and turn the ignition (but not start the engine) with my amateur hand-cut key. It was a little rough but worked if I jiggled it enough.2. Next, I went to a small town hardware store and talked them into copying the original key to the second blank key from this kit. They didn’t normally let people bring their own keys, but I agreed that if it didn’t work I wouldn’t blame them so they went ahead and did it for me. I now had two keys with unrecognized transponders. This second key was a much better copy and worked cleanly and smoothly every time. I’d recommend option 2 if you can find someone to copy it– but I did confirm option 1 worked for me, but would probably be pretty difficult without the proper files, vice, and calipers. It was fun anyway to try option 1 since this kit came with 2 keys and I could play with one.3. Next, I wanted to program the car to accept the new keys without having to use any unsupported software and risk locking myself out. Instead, I performed the normal end-user procedure using the following technique: first I wrapped the plastic end of the new, unprogrammed key with loosely crumpled aluminum foil, to block the transponder from being read by the car. Then I put it into the ignition while holding up the transponder from the old broken key housing to the ignition switch and turned to the On position without starting (the car thought I had inserted a working key because of this trick). Quickly I turned the ignition back off and removed the foil covered key and old transponder and then inserted the original working key, turned to ON for a second and back to Off. The car now thought I had inserted a second working key and was ready to accept new keys. Finally I removed the foil shielding and placed the new key by itself into the ignition and turned it On and then back off. This time the car read the transponder from the new key since the foil was off and updated the ECU to accept this key. The door locks cycled to let me know it worked. Now I had two working keys! Programming the second new key was easy because I could just do the “2 good key” process without having to use aluminum foil and the old broken key. I now have 3 working keys! I’m sure this trick would have worked even if I had two broken keys with good transponders, but it does require two good transponders (the transponder is a separate module in your key that doesn’t need batteries and is probably still working even if your keyless entry buttons don’t work since it is a sealed plastic box that gets power wirelessly from the RFID field in your car and would survive a lot more abuse than the keyless entry buttons, so if you didn’t throw away your old broken key, you may be in luck!)Programming the remotes was much easier. Just turn the ignition on and off 8 times real quick with one working key until it entered programming mode, then hit a button on each remote that I wanted to work one at a time. I now have two new working keys and two new working remotes, for a tiny fraction of the cost of paying the dealership or a locksmith. Technically I was able to get this all working at home without any professional help– but I would definitely recommend finding someone who can copy keys instead of trying to hand cut/file your own, unless like me you enjoy a DIY challenge.

Title: Very simple to program yourself!
Review: I bought these as a replacement for a lost set of keys for a 2010 Ford Focus.It’s a little daunting when you need to replace a chip key and programmed fob. You are at the mercy of the dealer or going to a locksmith, either way you know your going to pay a premium $$$.After calling two locksmith and a local ace hardware (yes, they order and sell these sort of cart keys) I received 3 quotes from $185.00 to $225.00 for 1 key cut and programmed and 1 fob programmed I decided that it was worth the $20.00 to give it a shot myself.I looked on Amazon and not only found replacement fobs and keys but I found out through the reviews that Ford built fob programming software into their vehicles and it sounded pretty simple to do.The package was delivered on time, packaged well and in good shape.When I opened the bags, each bag has a card with a website for programming procedures for hundreds of vehicles. I was able to download and print a set of fob programming instructions for my 2010 Focus but it turns out the YouTube video on their site has a lot more detail and was easy to follow.I read in one of the reviews that the 2032 button batteries were installed in the fob upside down and needed to be turned over. When I opened up my fobs, the battery was different in both. I looked everywhere to see which side is positive and which is negative but could not find any indication of the right way. Just so you know, THE POSITIVE SIDE GOES TOWARDS THE BACK OF THE FOB. (See picture)I followed the directions from the YouTube video and everything worked perfect. The four buttons, lock, unlock, trunk and emergency all worked fine and I was able to operate the fob from at least 50’ away through a closed window.I’ll give you the step by step version of the YouTube video guy:1- take the old and two new fobs into the car and sit in the drivers seat and close the door.2- lock and unlock the door with the switch in the armrest.3- placed the key in the ignition.4-keeping your foot off the break and without starting the car, quickly turn the key from off to on 8 times within 10 seconds, stopping in the on position on the 8th time. (doors will automatically lock and unlock if you did this right) if not start over.The car it’s now in programming mode.5- If you plan on continuing to use your old fob, start this next step by pressing any button on that fob.(the doors should lock and unlock automatically) next push any button on one of the new fobs (the doors should lock and unlock automatically) next push any button on the third fob (the doors should lock and unlock automatically)6- turn the ignition to off the locks will cycle again (you exited program mode)7- test your fobs to be sure everything works.I heard the dealer will cut and programmed the keys for $75.00 each but I’ll update if it’s different.All told, $20 to Amazon for 2 fobs and keys, $150.00 for the both keys to be cut and programmed= $170.00 for Two sets of keys and fobs as opposed to $370.00 from the locksmith and hardware store!

Title: FOBs and keys work fine.
Review: Received the remote key FOBs and keys quickly. FOBs were easy to program (8 on/off cycles until doors lock/unlock, then press a button on each remote). Range on these remotes could be better – you have to get fairly close to the vehicle for them to work. I took the key blanks and the one working key to a local hardware store and they cut them for $1.00 each. Programmed the keys to a 2005 Escape with an Autel MS 906BT. We now have three sets of keys/FOBs.You don’t have to go to the dealer and get price-gouged. Check with your smaller (local) hardware stores for the key cutting (big box stores usually won’t cut blanks you bring in – sometimes you get lucky, though). For programming, most shops have a decent scantool that can do the programming, or ask at an auto parts store if they know anyone who does side work. I usually charge $20 for key programming (or a case of beer – lol).I would buy these again.
