2002 Ford F150 XLT FX4 4.6 ltr.
Recently purchased and old owner had an extra key made it will go into the ignition and turn the truck over but will not crank it. I tried this key not realizing it was the wrong key about 5 or 6 times and now the truck will crank (with original key) and drive but will not shift gears (automatic tranny) also the overdrive light on the gear shift is blinking, I had a mechanic take a look at it and cleared all the codes plus remove the battery cables for 30 min. and still is happening what can I do?
If you purchased a key for the ignition it has to have a chip programmed to start the vehicle. I have one without a chip I hide under the car to use as a "lock out" key in the event I lock the keys in the car. It will open the door but do nothing else. Did you purchase the correct type key?
