Ordered for 2012 Ram pick up. Programming was simple and the remote works as well as the original. This is a very straightforward DIY for replacing a key fob. We also bought a separate key fob and the programming widget worked fine on the single fob. Highly recommend!

It worked perfect and the instructions for programming were easy to follow. Much more affordable than going through the dealership or a locksmith. It’s also a good savings compared to buying from the local auto parts store as well.

I previously bought a key on Amazon and it came with instructions on how to program it just using the car, but it didn't work. I'm not willing to pay the dealer a ridiculous $300 for a replacement key fob not including the cut key for the door. This item worked, but I still think the price is high. Pros: - I got a working replacement key fob for $100. About 1/3 of local dealer price. - The cut key from my broken key fob snaps into the Simple Key fob, so I don't need to have the key blank cut. Cons: - The programmer is a little too cheaply made. The little knob that you use to select the vehicle manufacturer just fell off when I took the unit out of the box. I put it back on and it just falls off again. - The programmer pairs itself to your vehicle so that it won't work with another vehicle. There's no reason for it other than to prevent you from reselling it or sharing it with other people. - The programmer only works with keys purchased from Simple Key. It won't program genuine factory keys or any cheaper OEM-compatible keys you buy. - The instructions are a little complex. For the price, customers shouldn't need to go through the key activation steps and the programmer shouldn't have a dial to set the manufacturer, it should just work. - The instructions aren't great. The key activation process refers to "the light under the panic button". See the photo. The light is located in the center of the blue circle. I don't know how that equates to "under the panic button". Additionally, the light is a tiny blue LED and it's fairly dim, so it's very difficult to see if you are outside, even not in direct sun.

Easy to install IF you pay attention to details and follow the steps in the noted order. I was able to program the included fob without any issues in 3+ minutes. A big help was watching the manufacturer's video. It's very good. My original fob would only start my car and the Panic button. The Lock, Unlock and Trunk buttons did not work. But with my newly programmed fob all buttons worked perfectly! IMPORTANT NOTE: The 8-key duplication "limitation" is NOT due to this product, at least in my case. The limitation lies with the vehicle's On Board Diagnostic computer (the OBD II connection). So, if the OBD determines that there have been a total of 8 fobs previously stored in its memory THE PROGRAMMING OF ANY NEW FOBs WILL FAIL! The only recourse is to go to an automotive locksmith and have them delete the previous (non-working/lost?) fobs. Now the programming of new fobs will work! In theory, IF you follow this step, you can reuse this product as many times as you like. DIRE WARNING Do NOT have the locksmith delete ALL the fobs! ONLY the ones you no longer have/need. If you delete all fobs your vehicle will NEVER start again. Or at a minimum it will cost you a lot to have it start again. If that's even possible.
