W202 Immobiliser Issues.

Away last Saturday for the funeral of a friend,I returned on late on Sunday. On trying to start the car the following morning I found the battery flat. My soon to be six year old daughter had apparently picked the key from where I keep it unlocked the car and spent time in it with the interior lights on. When she was done, apparently the rear door didn’t shut very well so the interior lights remained on draining the battery completely.
I have since recharged the car battery, changed the batteries in the remote key but the immobilizer won’t go off. The car has refused to start and I’m at my wits end. Saidieni!

hizi magari za teknolojia ya hali ya juu kweli zawasubua. my datsun 1200,kte ni kustuliwa tu inaguruma, even with a dead battery,. Inaeda inakuja imebeba mzigo ingine kubwa ya thara ya Ng’ombe
