Well believe it or not, I have never tried to unlock my doors with a key till today. I always used the remote to lock and unlock doors. Actually, I'm not sure a key was ever put in the lock. But I have 2 keys and neither one will manually lock or unlock the drivers door. It just doesn't budge. The key inserts in all the way, but that is it. My passenger side works perfect. Anyone have any suggestions on what to do? I was going to try some of that lock graphite lube and shoot it in the lock, but figured I will ask you guy's first. I firmly believe that a key has never been used on this truck being that I am the second owner and I know the person I purchased it from. Any help will be appreciated!

 

Is it possible that, given the cold weather, the lock is simply frozen? I don't know about New Jersey, but here in Massachusetts, it was 4 degrees this morning. If the passenger side works, try heating the key.

 

Definitely treat it like a frozen lock, could be moisture in a solid state. Otherwise known as ice.

 

I'll have to wait it out a couple of day's cause here in Jersey we are having overnight temps almost touching single digits. This was only a new concern because I have never used a key before!

 

I've never used the key on my 99 so I know how you feel!

 

Don't heat the key. Who knows how that will affect the resistor inside it. Buy a commercial lock de-icing solution (the type that sprays into the lock) and use it. Don't use graphite.

 

Sometimes I use my key on my 98, but it does not turn right after I put it in the lock. It seems that I have to wait a few seconds before it will turn. I am wondering if there is some unit in the lock that senses my key before letting the lock turn. Maybe I'm crazzy but it seems like the lock is looking for the code on the key befor it will turn.

 

Most likely a frozen lock. Do not use graphite, but do use commercial ice melter (alcohol) if you have it. Use a blank nonelectronic key if yoiu have it, heat and insert. Alternatve is hair dryer on low to blow directly into the lock.

The adage to keep in mind is "Use it or lose it"
Make a habit of going through and using every device in your vehicle at least once per month. Mechanical door locks, Emergency brake, 4x4Low, side windows, etc. Keep the lubricant spread and active or it will congeal with dust, especialy in cold weather. Use all parts frequently and they will be ready for you when you really, really need it during an emergency.

 

I've always shot WD-40 into the tumbler whenever a door or a trunk lock was sticking, then insert the key and work it back and forth a few times until it frees up. I'd have thought the passenger side would have been frozen up or difficult to turn as well if the problem was weather related. IMHO if you've never used the key in the driver's side (meaning the tumblers have never moved) I'd definitely vote for the WD-40.

 

If it is weather related, there's no way to tell which lock/locks or devices have resident moisture until it freezes. It is possible that one door may have a poor/leaking seal (in comparison)and may allow moisture in greater quantity or simply into places we don't like.

I'm just hoping that there's no moisture anywhere it shouldn't be this morning. It's -7 outside of Boston.

 

I wouldn't use WD-40 because it is oil based and it attracts dirt like crazy. When I was a locksmith i was called out because locks froze up and the customer said "I put WD-40 in it". Use lube made for locks.

 

Wow your 98 has a keylock on the passenger's side?

they must have stopped that in '99 i almost scratched the paint one night on the pass. side

funny no one at the dealership informed me of this

 

I'm right there with you DJFan,

I was working on the right side of the truck and realized the door was locked and I just had the key....without looking closely, I almost made a new hole for the key!

Who thinks up this stuff???
