2002 Ford Taurus keyless entry

Sounds like they might have missed plugging the door harness in to the body, or maybe left a ground unhooked.

Hello: To resynchronize the keyless entry close all doors, key out of ignition. Hold lock and unlock buttons till the doors (all) lock then unlock. If the transmitter still doesn't work you have other problems. Go to auto zone they can check your transmitter to see if it is working.

have remote checked out at advance auto,could be ur keyless entry sensor bad

Try it with a new remote pad, turn the key back and forth untill the locks jump up and down.. do it slowly , when they jump make sure to leave the key in the on position while pressing both lock and unlock buttons on the remote, they should then jump again telling you that the remote is now programed.

Do you mean the remote fob or the key pad on the side of the car. Fob could be batteries.

The keyless entry matches to the module for it that is mounted under the dash. It may have gone bad since your remote will not function. Of course it could be your remote as well that went bad

I have a 2000 ford Taurus and my keyless remote has stopped working and having problems with key unlocking the door from outside, none of the remote work do u have any idea what my problem could be ?

Sounds like the keyless entry system is on the fritz. You will probably have to get a new brain for the keyless entry system.

fords are notorius for faulty fan switches, you will need to get a new one, but it will probably fail in a year or two.
