The coded key probably needs to relearn. Turn ignition to crank and release. Let sit in on position (engine off of coarse) for a full 10 min. turn off for 30 sec. and repeat 3 times engine should start. This procedure should take 30 min. so a booster is needed to maintain a full 12 volts. Do not attempt w/out a charger connected;
