Review: Good - Good
Review: 2007 Mercury Grand Marquis replacement key. - Great replacement transponder key. I bought these for my 2007 Mercury Grand Marquis. Locally, a key made whether programmed or not was close to $100! These were a great value! I was able to purchase these 2 keys for under $13 and my local hardware store charged me $1 please key to cut them. I must caution on programming. If you have 2 working keys, you can program extras yourself. If not, you'll need to have a scanner that can access PATS system of the vehicle to program the key. There is no work around. I knew this ahead of time. I only had 1 key. Once my keys were made, I headed to my buddies shop. Here, I used his snap on scanner to program the 2 new keys. These are 80 bit but are backwards compatible with the 30 or 40 bit system my 2007 uses. Works perfectly.

### ⭐⭐⭐⭐⭐ Inexpensive alternative to dealerships
*by S***N on 27 August 2026*

Works as expected! Saved a lot of money by not going through the dealership. Had my local key-carving guy do it (it didn't quite fit in his machine, so he kind of cheated by doing it backwards), even though the keys come with a resource for qualified professionals. Programming the newly carved keys was super-easy.
