I bought a truck from a friend that was losing it in inpound. When I went to pick it up at the inpound yard. We unlocked it turned it on backed it up. Turned it off, left the doors open and had to take the battery out for some reason. Well now my doors are stuck locked. I have tried using the key and the door look botten on both doors. I can hear it going ckick click as I push it. And with the key it sounds like its doing something. But its not. How can I fix this myself. On ssi can, t afford to take it to the shop.
Do you

Yw both doors are open.I can't shut them. There open. The thing that latches and keep them shut is in the lock position and won, t unlock. O I can, t shut my doors. As I said I tried the remote lock and thw one on the inside of the truck. Plus I uesd the key on the outside. All it does is make a clicking noise. I can, t afford to take this to a shop. My other car is a 2000 chevy blazer LS and the main bearings are going. Out on it. So I, am saving to fix it. So I don, t have a car right now and having to pay people for rides. If you could coul you explain in detail how to fix it. That is if you know whats wrong, Thank You

Try a key relearn on it. May have to connect battery charger on it during process because it will drain battery. Turn key to on position for 10 minutes until security light goes out on dash, turn key to off position and take out for no more than 5 seconds then back on for 10 minutes, then of for 5 seconds then back to on for 10 minutes. Do not attempt to crank during this time, will reset process. After last 10 minute on time then attempt to crank.

I followed your instructions to the t. Timer & stopwatch even. I am sorry to say it did not work. I am not sure what its called but the passenger side. Where they connect. There a thing that like latches over when the door shuts or locks. Well that one is stuck in the down position. The driver door is stuck in the up. The opposite of the other side. My husband said something about a actuator. Would & could they both go out at the same time? And if so how do I replace them? How much do they cost? And is there instruction that are printed out instwad of video. My service is to slow to watch a video. Also again thank you so much for all your help, its a god send thats for sure.

You may have to remove door panels to get to open latch rods. Should not be this difficult of a situation unless key is wrong or door locking linkage is messed up. Best thing to do at this point is to remove door panels and look.

Again thank you for all your help. Also what tools will I need to do this?

The pictures you sent do not reflect the truck that I have
The truck that I have is a 99 GMC seirra 2500 3/4 ton 4x4 ext cab long bed with a 6in body lift. The handle and arm rest are all contoured. Were the latch is on the side there are 3 bolts. The latch it self is plastic inside. And the doors then self are all electronic. There are handles to open the doors but no handles to roll down the windows. Sorry that I can't use what you have sent but the door handles do not come off like that.

Sorry, just sent info of what I presumed it was. There should be 2 screws at bottom of door. Window switches should pop out of door with a screwdriver. Remove top extension on opposite side of mirror. Mirror switch should pop out as well. Should be two screws holding arm rest/handle in. Two screws behind plastic trim which is behind interior opening handle. After all screw removed it will either slide up or have to be pried off with long flat screwdriver to disengage clips from metal.

Peel back the plastic and check the link rods to the door latch and handle. See if they move.

There was only 1 screw on the bottom.I was able to lift the door panel up but not off
I did see that the latch itself is broke in half. You would think that for the price we pay for a car or truck we would get alot more metal. The darn things plastic.I could not get the door panel off even half way and I
Could not put it back on either.I did see that there were 3 screws holing it on on the outside but as for the inside. That I, m not sure of.I could only lossen it enough to get my hand in a little bit. So I guess it a trip to pick-n- pull for my. The gm dealership wabt $246 fo a latch and I can, t afford that. Thank you for all your help, Nancy

Sometimes there are pieces of trim that you can pull off to access the screws. Part pulling is the best option for that. Dorman also makes a product line called Help. They make many door handles and latches. You can get them at parts stores such as O'Relliy's.

Is the latch hard to put on. And when I tried to put the the door panel back on I could not get the left side to go back on.I double ckecked for more screws. There was no trim hiding anymore. I think its just the clips that are keeping it from going on and off.

There are 2 nuts holding the handle in place that can be removed with door panel off. Tricky part is getting all the rods back connected. Door trim panel has several plastic retaining pegs. Sometimes putting them back the pegs get bent. I usually just the line each peg back up while putting panel back on. Just takes some time and patience.

Sorry that I haven, t got right back with you. We have had so much rain all the small streams in our area are flooding. It, s been raining cats & dogs. Plus we don, t have a carport towork on the truck out of the rain. You said something about rods. Do the have to be taken off to replace the latch. I know the latch has 3 large screws on the outside of the truck to remove the latch. And as for the door panel I was able to lift it up. But I could not get it to go all the way back down on the bottom. I can, t believe they made the latch out of plastic. Again thank you for all your help.

Yes you can disconnect the rods when you removed the 3 bolts holding latch. Usually just the plastic clips break that hold rods to latch arms. Sometimes you can get those at auto parts stores. Dorman products make a line of replacement parts called Help! They usually make those small plastic clips and things that break easily. As for the door panel just keep trying. Nothing I can tell you without looking right at it. Its a pain but just keep trying different angles or move harnesses.
