First time post. Tried to take my 2006 S 3.0 out of the garage this morning (been resting in there a few weeks) however I was foiled. Tried unlocking with the remote as usual - nothing. Tried turning the key in drivers door lock - nothing. The red alarm-set light is flashing on the dash board as normal. Any suggestions? I am planning to get into the trunk and hopefully just need to charge the battery. Does this sound like the solution? Also will alarm go off and alienate me further from my pick up truck neighbors?

 

Welcome to the forum Keith,

Please post an intro in the new members section when you can.

The remote not functioning sounds normal after an extended period of non use, but the key should work as normal regardless.

 

Will do on the Intro.

That's what i thought but keys wouldn't turn.

 

Squirt some lubricant into the lock

 

So you don't think its battery related? battery is new but car has stood in garage for about 6 weeks. Also temperature gets down to just above freezing in there.

 

Sounds working (PATS flashing etc) except the key should open the driver's door.

The battery sounds good.

You will trigger the car alarm if you remove and refit the battery!

And will need to get into the car then put the key in the ignition to shut the alarm off.

So, you do not want to take the battery off!

 

Sounds like two issues going on.

1) Definitely figure out the problem with the key not being able to unlock the door or trunk, as that should work regardless of anything electrical. The lock cylinders may be seized from lack of use.

2) After 6 weeks, your battery may be severely run down. Not sure of the exact logic, but your car may have automatically shut off non-essential features (such as the key fob interface) to preserve the alarm system. And since the key doesn't seem to work, what can you do? Scroll down to post #3 in this thread, to see the +VE connection aft of the right front wheel:

Use that connection to hook up a battery charger overnight. Once the battery is back up to snuff, see if your key fob works again. And then take care of the issue with the keys.

If you don't drive the car very often, I'd highly suggest hooking up a battery tender. That same thread had good details on one method to do so.

 

I don't believe the fob will function until the key lock has been cycled?

 

The car does shut down more and more - including listening for the fob. (If all else fails hunt through the tech stuff which does document such things.)

The fob MIGHT work if you can wake the car up. But it might not and meanwhile the alarm may be sounding (depending on what was done).

 

This seems like the best first plan.

The car may wake up if you disconnect then reconnect the battery.
Have you tried the key in the boot lock? The alarm will sound if you open it.

 

Got home from work and can confirm manual door lock not working - possibly from under use so will be lubing it.

Got into trunk with key and as expected the alarm started. Went to passenger door - pressed fib button to unlock and doors unlocked and alarm reset.

believe it was all down to drained battery. Thanks for the help and not to buy a battery saver. Any advice on a good one as this car will be in a very cold garage over winter.

Thanks again
