Hi I have a GL 550 and the battery is completely dead and doors are locked I can not get into the vehicle and I can not jump the vehicle to or jump start the battery. What I need is help getting into the vehicle does any one have any suggestions on how to get in to my vehicle. Thanks
I tried the mechanical key it will not turn enough to unlock the car.

 

There’s an actual key in the key fob.

 

Use the actual mechanical key in the fob to open the driver door.

 

 

I’d suggest replacing the auxiliary battery as well when you replace the main battery.

 

My auxiliary battery is original to the car. Not sure how it has lasted 15 years but it's still ticking. But, yeah, not bad advice to change.

the mechanical key did not turn enough to get the vehicle unlocked manually

 

Spray a bit of lubricant in the keyhole. WD-40 should do the trick if you don't have white lithium grease spray or something. I'm guessing it's seized since it's probably never been used.

Then stick the key in and work it back and forth a few times. It should start loosening up.

 

DarthVaderPA provided instructions.

You turn the key and hold it there and pull the handle. Pulling the handle should pop the lock...at least according to those instructions posted above.
