Open trunk ls remote valet

try putting pressure on the trunk then pressing the remote...somtimes they get jammed.

I have on 07 is250 and the power windows and trunk release were not working. There is a trunk/valet button in the glove box that needed depressed in order to make them work again.

I am guessing the button in the glove box is not working. You may want to check the fuse for that.
If you can get to the trunk from the back seat, there is an emergency latch inside of all trunks per government regulation.

What do you mean by "my trunk button"? Are you referring to your key-less remote? Or the yellow button in the glove box? First check to make sure that you have not accidentally set the valet switch to LOCK. That will disable the remote & the yellow button from working. Info on how to do that is in your owners manual.
FYI, there was a technical service bulletin on your key-less remote. Buick redesigned it [they had problems with the trunk opening accidentally] If you need a new key-less remote, the new part number is P/N 25678792.
If the solenoid for the power trunk lock has failed, the remote will not work. Assuming you can not open the trunk using the trunk key, there is one last method to get into the trunk. You must remove the rear seat assembly. Then remove any plastic or paper covering which may separate the trunk from the rear seating area. Using a good flashlight, a 3/8" drive ratchet, several extensions [totaling 3 feet in length} and the proper flex socket [most likely 8mm, 10mm or 13mm] you can remove the three bolts which hold the latch mechanism from the inside of the trunk lid. The trunk lid will then open. At this point, you can get your stuff and fix the problem with the power trunk mechanism.

Hello: Open the glove box and see if the valet switch is in the on position

Brake light switch. Should be against brake pedal arm under dash. May be loose or need adjusting.

Your Valet cancel switch is set.


Open your glovebox and you will see a pushbutton on the the left side, if memory serves. When this button is set, the power button will be disabled, but the key fob button will still work.
This is for when you Valet your car, you push the cancel button in the glovebox, lock the glovebox, then give the Valet your Valet key, which will not open the trunk or the glovebox. Voila, no Valet rummaging through your trunk :)

Often full gloveboxes will be the cause of the button getting pushed accidentally.

Some cars have an over ride switch in the glove box, which allows you to lockout a valet. You simply shut off the switch and lock the glove box and the valet cannot access the trunk without the master key to unlock the glove box. See if you have one that has been shut off by mistake.

There is a trunk button in the glove compartment. This is designed to keep the trunk "secure" when a valet takes it.

Make sure the switch is on and not off. Also be sure you don't switch off the front passenger air bag as that switch is also in the glove box.

There's a switch in your steering column. must be replaced
