Review on 🔑 Set of 2 Key Fob Keyless Entry Remotes for Ford, Lincoln, Mercury, Mazda - CWTWB1U331 GQ43VT11T CWTWB1U345 4-btn by Zach Peterson

So I figured I'd just have to take out the cases on the keychains and put the guts of my old ones in the new ones (they're old, worn out, and one is broken where it should be attached to the keychain). When I opened the first set I found to my surprise that each key fob comes with a circuit board and a new CR2032 battery (although not the same brand but I'm sure it will last in these). I learned how to program remote controls from Google in five minutes. Now I have four radio key fobs. Just in case, I'll keep one of these in a magnetic box under the car's chassis. This is a killer deal! Many Thanks. Honestly, you can't even get a CR2032 at Walgreens for less than these keychains, and they came with them!
