Battery went flat now wont take key code in drivers door 1994 p38 range rover.did some engine work battery disconected for about a week. when engine work finished.conected batery started fine. went shopping ,came out batery flat key code lock out. tried procedure with key code in drivers door . help please

no year car told and worst no engine told and is an engine question.
1994 to 2001 made. 3 engines 1 is diesel,2.5 BMW
any car that will not start ! the driver cranks the battery dead.
so sure it can NOT start THE ENGINE now.

the shop manual says in this case keep the battery charged
to diagnose all fail failures, EFI,engines or all electrics
resetting the BCM does not fix this.
yes pulling battery neg lug for 15min and back on resets computers.

there are 6 to 10 causes of a dead starter motor, and battery dead or loose rusty lugs tops the list,
ever jumper cable , jump start a battery? call the AAA AUTO CLUB AND SAY JUMP ME rovor?
NOW IF THE BATTERY WAS CHARGED AND WE CRANK IN PARK WE FAIL WE CRANK ALL CARS IN NEUTRAL , SEE IT DOES CRANK?
HEAR THIS , THIS CRANKS BUT WILL NOT START

WE CAN NOT HEAR YOU CRANK YOUR CAR, DEAF AND BLIND IN THIS TEXT BOX.(ME)
IF IT DOES CRANK FAST, THAT IS A NO START ONLY !
WE SAY CRANKS FAST BUT WILL NOT START. (BATTERY GOOD)

AND HAS UP TO 50 CAUSES AND 20 TESTS AND TOOLS TO FIND IT. (CHECK ALL FUSES. AND SCAN THE OBD2 SCAN PORT IS FIRST.
THE CAR NEEDS SERVICE FOR SURE.
the only tool less tests are
fuses
and cranking in neutral.
just 1 eye and 1 hand does it.
ok one more engine oil all leaked out. engine seized.grin! dip stick dry, via Mark one eyeball check/.

There is a sequence of left and right turns of the key in the driver's door that will reset your bECM (Rovers brain) if the following have been tried.
1. Replace batteries in remote and 're-sync by depressing lock button on remote while physically turning and locking the door. Don't release button until locked and key removed. Repeat for unlock button.
2. Disconnect negative/earth cable from battery. While disconnected open driver's door, turn ignition to position 2, return to battery leaving driver's door open and reconnect the negative cable. Proceed to ignition. Turn off completely. Close all doors and hood and attempt starting.
Should both of these methods fail, run a search here on fixya for "engine disabled Range Rover P38" This will take you to step by step instructions on resetting the bECM which I opened this post with. It has been covered many times here, including by myself, no reason to post it again.
Good Luck!

I have the same problem sometimes
1 Check the condition of your battery, if old, it will not give full power required to communicate with the security system.
2 If you don't have the EKA of your RR, try this next time you get caught, put key in the drivers door look, press unlock button on key fob and at the same time turn to unlock, if all locks unlock then the engine should not be immobilized - Good luck

Lock doors with the key. Take out key . Insert key open and close lock 5 times then on the fifth turn open door this will reset the disable code to normal . I had this code on my P38 Range Rover and the Rover Tech assisted me with this simple way to reset the engine disable fault code . Good Luck .

need to re-sychronise the key put key in door lock hold button in on fob and turn then back to middle and let button go if it worked the hazard lights will flash. if you got a handbook it will explain it better

The BECM will retain the EKA code, so , charge or replace the battery. Close all doors, windows bonnet etc, then try the EKA code. You must know, that if you enter the incorrect code or do not enter the code correctly by returning the key to the centre position after each turn of the key , more than 3 times, then the system will lock out and you will have to wait 30 minutes to retry. It should start , but it would be good to get another remote handset, Hope that helps

sounds like keyfob has lost its sync with the car, look online lots of places tell you how to re-ai.lgn them

hi i have a range rover p38 2.5 diesel it starts but wont drive when you put in drive

make sure you disconect the battery or the computer still reads that the circuit is open and will fry a perfectly good coil. I had the same issue and had to do a second time. Disconected the battery and now no problems.

This car is in super lock mode... when you press remote 2times to lock or when you lock with remote and try to unlock using key manually.

there is a 4 digit number to open the door, its like opening a safe, starting from the left(key in car door) it goes L/R/L/R. so if number code is 1234..... left 1, right 2, left 3, right 4.

or if this too troublesome you can ask landrover dealer to remove the KEYCODE.

happy trying.....
