KeylessOption Car Key Replacement for 2000-2017 Ford Lincoln Mazda Mercury Ignition Transponder, H84 H92 40 80 Bit - 2 Pack

Awesome price and worked well. Had a local locksmith cut and program both for $60. Compared to over $200 at the dealer for one I'll get these two more times before I go to them.

Quality keys. Works great. Original key keyring tab broke. Had to buy a transponder programmer and to copy my original key but it programmed it without any problems. Definitely cheaper than a locksmith or dealership.

Worked well on my 2007 ford exploerer

rapid delivery, good price and programming per owners manual was seamless

I have a 2002 Ford Explorer Sport, which uses the same type 9 key as a 2001 Ranger. It is compatible with either a 40 bit or 80 bit H84 key. So in theory these keys should work. However, I believe that the antenna in these cheap keys is far too weak to be picked up by the car's transceiver. When I read the PATS module, it only throws a code indicating that an unauthorized key was used maybe 1 in 20 times I try these keys. I had to waste $30 on having a professional locksmith cut these only to find out that they were too poor quality to function. My car appears to be a little picky, as even the OEM key that I had to purchase from the dealership is a little flaky at times, but my original key works every time no problem. With the money and time I wasted getting these cut, I'd recommend just buying a key from a dealership, they only charged me $50 for an OEM Stratech key and no cutting fee. You can do the programming yourself.

Great price and quick shipping through Prime. I bought a two pack for our son’s 2007 Ranger. Had keys cut at Lowe’s. One key was successfully programmed and works perfect. Unfortunately the second key did not work at all after multiple attempts. Only option is to return therefore I will keep since it’s cut and deducted one star. My suggestion is to buy the two pack just incase. It was super easy to program. Also DO NOT fall for the QR code scan on the package it has nothing to do with the remote programming.

Works fine once it was cut to fit my 2010 Explorer and I programed it per instructions on internet and YouTube. Had trouble finding somebody to cut the key. Ace hardware stores want you to buy their key for $100+ to make a duplicate transponder key. Home depot will make a non transponder key for $5 that will unlock the door, but does not start the car. I went to Lasco Ford, the local dealer and asked about cutting my blank that I bought here with the transponder. The smart ass counter guy said he would try, but it may not work. No mention of the cost. After a few minutes he came back with my key and a bill for over $21. I programed the key per the internet instructions using my other 2 working keys. and it works great.

I see from the reviews that they do seem to work great for some people, so I gave it three stars for benefit of the doubt. Maybe it's just my car. But...let me you why I think it's not. I bought keys twice to find out for sure.My car is a 1998 Lincoln Town car, 79k and beautiful shape. Always taken to the dealer for everything, garaged, detailed well kept. it was a rich grandmas car, so not abused. The car only came with one key when I bought it from the original owner. It's an original factory key, not a copy. I know on this particular car, if you have TWO programmed keys, you can use them to program more keys yourself. Since I only had the one key, I was prepared to have them programmed at a locksmith knowing this.I bring the keys to a locksmith to cut and program. Three keys get cut, NONE will program. Well crap can't really return them since their cut. They work on the doors and trunk so still useful maybe...? Nah, I want it to start too. Off to the Ford dealership I go!I ask the service manager to program the keys, telling him the locksmith cut them, but wasn't unable to program them. Programming will cost $65 bucks a key. Cheaper than the AAA I don't have, let's do it.After a solid hour in the waiting room, their tech comes to tell me the keys won't program. I tell him "Yeah, the locksmith said they wouldn't either" The tech gets grumpy with me saying I "You didn't say someone else tried already. I though they were blank" Umm...yeah I did. I told your boss dude! He tries is again and is convinced that it must be that the locksmith "screwed up" the keys by using a cheap programmer or something yadda yadd yadda. My new keys are "bricked". Not sure it works like that but ok.So, I order two more keys, This time I don't even OPEN THEM, (I don't want to hear how they won't program because I walked to close to a microwave or something...) and I take them directly to the for dealership and again, same thing. I break down and buy a $75 FORD key (looks exactly like the ones I'd ordered BTW) w/ another $65 to program it and it works just fine.Now that I HAVE two programmed keys, I plan to try and program some of these "duds" myself and see what happens. if it works, I will update.
