I dont know the keyless entry code to my 1990 lincoln continental how do i figure out the number?

The MASTER CODE for your keypad entry (I believe that is what you are talking about) can be found on a sticker on the hinge of your trunk, passenger side. It will be five digits.

It sure sounds like a fuse. You can check for proper voltage at the hot wire of the actuator while you try to pop it. I think you are overlooking the fuse. Make sure the actuator has a good ground as well.

You do not say what kind of vehicle and why the dealer could not issue a new key using the VIN. I know of no manufacturer that writes down the codes anywhere in the vehicle. The keyless entry is controlled by it's own module and is verified by the main computer. The ignition key carries the code on it, and is verified by the ignition module. A good locksmith shop should be able to make keys for you.

Hello! You have to get your documents together, write down the VIN # and go to the dealer. They can help but it might take a day or two for Detroit to answer.

Open the right/rear door. Pull the rubber weatherstrip back from the door opening. Fold the right/rear seat back down into a locked position, in order to access to the right/rear trim panel. Carefully, pry the right/rear upper trim panel housing the right/rear seat belt height adjuster. Now carefully pry back the lower trim panel taking care now to break it, exposing the vehicle security module with three connectors plugged into it, coloured green, blue, and grey. Look on the label that has the part number which should end in EB. There are FIVE numbers to the right of that number. Those five numbers are your keyless entry keypad code.

After entering the 5 digit code that is currently installed, press the 1/2 button and enter your new 5 digit code. After entering your new code, press the last 2 buttons (7/8 + 9/0) at the same time. This will confirm your new code has been accepted. Keep in mind, in case of loss of power, the keyless entry will revert back to the original code. Best of luck.

Check inside the trunk lid for a label with a 5 digit code. If unsuccessful, then any dealer would be able to help you by checking the VIN number.

Enter the keyless entry code on the door keypad 3 times. Locks will cycle down and up after the third time. Press and release the "lock" button. Locks should cycle again. May need to hold down lock button for 2 sec rather than press and release. Program up to 4 remotes. If cycling the key on-then-off works, you'll probably have to do it quickly 8 times and after the 8th time, locks will cycle down then up and press and release the lock button.

I have heard rumors that there is a number on the frame underneath the passenger side of the vehicle. Supposedly the last four digits are the unlock code. I will research and post further. You can take the VIN number to a Ford dealer and they can cut you a new key for a nominal fee.
