Lock/unlock doors

[menard.jacques@gmail.com]

All of a sudden, I can not lock all doors with my remote key, but can unlock only the driver door
Very hard to understand. I can not find any electrical drawings for lock/unlock doors and mechanical drawings as well.
I'll really appreciate if you can help me

Not being a smart a$$, but check the battery in the remote.

The remote could also just have a bad button after that many years, as that is pretty common.


Next would be the lock module that processes the information, if the van has one and not built into some other computer.

Sometimes the buttons can be "rescued" using aluminum foil - but they're cheap enough to just replace now.

And I thought aluminum foil was only good for "fixing" blown tubular fuses

Thank you very much for your quick answers.
I'll change my battery first (will get them tomorow and come back to you)

Been "messin'" with Buttons?

In my 2008 Chevy 2500 (RT170P) there are a couple of buttons on the dash - driver's left. The third down from the Top is called the "Feature Key." There are a number of things (it appears) you can do. I have not, but it could be something for you to try. The bottom button (Number Four) is the Check key.

Here are a few of the options you get when you scroll through. First option is on the bottom, then subsequent above, until the Factory Reset.

Can't say this may solve your problem - but worth a shot. Excuse my phone images.

Cheers - Jim

I found the problem. When I had maintenance done at the garage last week, he opened the fuse box under the driver's bench and looked for the fuse for the rear lights. When he removed fuse #15 (the one for the door locks), he put it back in the wrong position (#16)... et voila
Thank you all for your quick comments, I've really appreciated

Remote

Hi, on my remote it takes two clicks to open all doors. If you click it once it just opens the driver store. Did you try that?

also good for wrapping up an easy pass so that it cannot be read, and of course as a hat to avoid covid!
