I bought an S430 couple days ago. The guy who delivered the car locked the keys in the trunk and the battery is dead[:@]

IS THERE ANY WAY TO OPEN THE TRUNK OR GET INTO THERE?????

ANy help would be greatly appreciated, thanks!!!!!

 

You will have to order a new key from mercedes or worse break into the trunk. To order a key u need to prove u own the car and have the VIN number.

 

but you can open the door and hood?

you can make jumper via starter cable. it will energize the car and you can use remote trunk opener.

 

how can i jump start it from under the hood???

 

yes. reach down to the starter cable.

also...
to unlock the car, you need to apply pressure on the PSE pump hose beneath the right rear seat. (vacuum to lock them).

 

anyway...the car is:

126?
140?
220?

i feel like a blind man guessing what model you got.

 

I had the same issue with my 300C, I closed the trunk while installing my Nav. Since there is no external key slot in the trunk and the battery was disconnected I had to crawl through the fold down rear seats and pop the glow in the dark E release. It would have been easer to jump it from the redundant bettery terminals under the hood to energize the dash trunk release button.

 

I have a 2004 S430
...and by the way you guys can give me a hint where the pump is or battery terminals under the hood, battery terminals seem to be under the ECU"s am i correct????
sorry new to Mercedes, worked on VW's a lot[:@]

 

ok found the battery terminals, now where do i need to apply the pressure to open the trunk????

 

W220!

nope, you can't. only on W140.

your PSE combined is inside the trunk as well.

your key is also a keyless-go.

once the car is powered up, just step on the brake and start the car using push start button.

release the trunk using that remote switch near your door pocket behind the window switches.
