It only turns on for ten seconds then it turns off

Shut the truck then put the key in the door turn it right for ten seconds and hold it after ten seconds turn it left an hold ten seconds then unlock the truck and try to start agin this will reset the theft system

If you have the original key.. Turn it on (don't try to start it) for ten minutes, turn it of for ten seconds. Try to start. If it doesn't start you have to do a relearn. Ten minutes on, ten seconds of, do this three times, then try to start it. You will have to have a charger on it. because if the battery gets to low, you'll have to do it all over agian.

Try holding down the power button for ten seconds, the press at the same time, the left shift, option, an control buttons at the same time. Hold for ten seconds an release the three but continue to hold power button for ten more seconds. Its a reset.

These vehicles have a built in antitheft system. When switching the ignition you interrupt this system. You will need to do a system relearn after the new ignition is installed. It will not start until the new ignition is installed and relearned. Step one. Put key in ignition, turn forward 2 clicks until right before it should start. Keep like that for ten minutes, NO LESS. Step two. After the ten minutes, turn key back to off position for 5 seconds. You need to do steps 1 & 2 a total of three times in a row without trying to start the car in between. The whole process should take roughly 30 minutes. After the last time waiting 5 seconds in off position, turn key forward and attempt to start the vehicle. Remember no less than ten minutes when forward, maybe do ten minutes and 15 seconds to be sure, some people even do 11 minutes.

Sarahmorse21,

At risk of sounding silly, did you hold the Home and the Lock button for 3 seconds to turn it back on?

you can get a new key from a dealer and program it yourself by leaving the key on for ten minutes and the security light turns of then you turn the key to off for ten seconds and turn it back on and the security light will come back on for ten more minutes you do the turn it on and wait process 3 times and the light will go out the 3rd time and you can turn the key off for 30 seconds and it should start after that. some times they will work after the first ten minutes.
