My door would not unlock using the remote, so I used the hard

Customer Question

My door would not unlock using the remote, so I used the hard key. An alarm went off inside the car (outside is silent). Now the car is on lockdown. No lights come on and the key will not turn in the ignition.
JA: Sometimes things that you think will be really complicated end up being easy to fix with Mercedes. The Mercedes Mechanic I'm going to connect you with knows all the tricks and shortcuts. Are you hoping to fix this yourself?
Customer: Yes
JA: Great! What have you tried so far?
Customer: Pressing every button on the remote. Changed the battery in the remote. Tried putting the hard key back in the door lock.
JA: Is there anything else important you think the Mercedes Mechanic should know about your Mercedes?
Customer: No
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Mercedes Mechanic about your situation and then connect you two.

Hello, what year and model it sounds to me like the cars battery is dead, the alarm is most likely due to the low voltage and the alarm is telling you to put the shifter into park. so what year and model are you working with?

My steering wheel is locked and the key will not turn in the ignition at all.
Expert:  Lou P. master tech replied 1 year ago.
hello, sorry we keep missing each other, ok so im pretty sure you have a dead battery, where did you try jumping the battery at? under the hood on the gold post and fender post?
Customer: replied 1 year ago.
I tried with my neighbors truck under the hood. When I went out the morning, the alarm sounding on the inside stopped but as soon as we hooked up the cables it came right back on. The steering wheel is lock, the key will not turn at all, the brakes are locked and no lights or anything come on.
Expert:  Lou P. master tech replied 1 year ago.
ok, that means that the jump start will help but the battery is extremely dead.
Expert:  Lou P. master tech replied 1 year ago.
if the beeping came on when the cables were hooked up that means that the power was getting into the cars battery but the battery is so low that it would have taken a few hours to jump it. do you have access to a battery charger?
Expert:  Lou P. master tech replied 1 year ago.
if you do a mercedes road side assistance call they will usually come out and jump start for free even replace the battery for a small charge.
