how do I find the keyless entry code for 2000 mercury grand marquis
See if you can find this from Mercury using your VIN number.
Visit your local Ford Dealer with your driver's license and vehicle registration, for proof of ownership. If your code is still on file they can use your vehicle identification number (VIN) to get it for you. HTH. -Jim
If you can locate the module that controls the keyless entry the 5 digit number is usually on a label on the module. You can also, as js08016, visit your local Ford dealer and they can extract the number from the vehicle's ECU. There will likely be a charge for that.
