I went to get into my 2005 RR and keyless entry wouldn't work.

Used the key to get in driver door, noticed no lights and can't turn key in ignition after turning steering wheel.

Any ideas?

Battery? Security lockdown because of a key malfunction? Electric failure?

I can't even roll it out of my garage...

 

Combination of both. Weak battery / bad battery connection - while vehicle locked - immobilization triggered.

 

your battery is stone dead, good luck getting it to jump. when its that bad those bmw batterys don't like to take a jump from a small jump pack.

You might need a new battery to get it going.
