Hi,

new to your website. I am frustrated. Accidently left deck lid
open on 2008 challenger srt8 and drained battery. Disconnected
battery to charge. when i reconnected battery, car won't start
with key fob. Did actually put key in ignition thinking that would help.
Hate to call the dealership tomorrow if i don't have to.
This is embarrasing.

Welcome to the forum. you might want to check and maybe clean the battery connections and make sure the battery did acually charge.

You should show 14 plus volts with no load on the battery when its charged.

Not clear if you have a battery of fob problem from your description.

Do your interior lights come on and when you try to start everything goes out and the car does not crank

or when you try to start the lights stay on and you get some message in the display about the fob?

Make sure battery terminals are clean and tight. Take the start button out and try the key. Either charge the battery or get a jump. Anything over 12.2 V DC is good with no load, it should not drop below 10.8v DC when you crank the engine, then when it starts you should see it go over 13V DC and come back down as the battery recharges. Also rmember to always disconnect the negative {black} cable first. and reconnect it last.

This is what happened to me. Car won't even crank. Is it a security feature? I've tried jumping it and charging it.

Well, we found out the other day that if you put the fob into the dash the engine will run even if there's no battery in the fob. So try starting it by putting the fob into the dash and if you don't get anything that way I would then clean the connections on the battery terminals. If nothing then, it may be a bad control module, and you would need the dealers help for that.

Tried inserting the key fob as well and no difference. So it must be a dealer issue? I believe I still have it under warranty.

I had my battery totally discharge twice because the trunk lid accidently popped open under my car cover and stayed open with the light on for 7 days.

I disconnected the battery and put it on a charger for 8 hrs. and it turned over the engine fine both times.

I think your battery is shot- it is over 4 years old. Time for another.

Important- Make sure whomever installs a new one vents it properly.

What do you mean by venting it properly?
