P38 2.DT auto KEY CODE LOCKOUT

Hi Guys

Need help. My battery has gone flat which I think has been caused by my home wireless router and I do know that the old RFunit will have to be replaced. My obvious and immediate problem is how to get back into my p38 without setting the alarm off.

I know that there is loads of stuff on here about this but can someone please post an idiots step by step guide. Please start from me putting the recharged battery back onto the vehicle. I have then shut the bonnet and the car has locked all the doors itself, on the display screen it says KEY CODE LOCKOUT. Please post a step by step way to get back into the car. I do have my EKA numbers. What do I do next?

Thanx guys. great site !

Connect a jump start battery across starter motor and an earyh point ( the correct way aroind). Leave it 5 mins then open door, bonnet.

This happens to me all the time, you should have a four (4) number code. Pleace the key in the drivers door lock and turn it 4 times to the left. Then using your code turn it the first number to the right, then the next number to the left, next number to the right, then the last number to the left, finaly turn it once to the right this will reset the code

dont forget to watch your lights, when you do your four unlocks, your indicators will flash to let you know its ready for the code, then, when you do your turns entering your code, the headlight symbol between the speedo and the rev counter will flash with each turn, to let you know its going in o.k.
good luck.

Thanks for the replies.

I have now sorted this problem. My P38 is a 98 model and I understand that LR updated the system to be a little better than the earlier models. I put the fulyl charged battery back onto the vehicle. I shut the bonnet. The car locked the doors by itself and the dashboard display confirmed KEY LOCKOUT. I waited for 30 mins and the dashboard error message cleared. I then put the key into the drivers door, pressed the alarm set button on the fob at the same time as turning the key to the left. I held for five seconds in this position. The car alarm beeped twice. I then returned the key to its normal centre position. This unlocked the door. I opened the door and put the key into the ignition. Turned it to the right but I did not start the car. Turned back took key out. Got out of car, shut the door and everything was back to normal. All I had to do was to reset the windows by opening and closing them in order to satisfy the fault messages on the dash.

You may be interested to know that I had installed an electricity monitor meter on my domestic electricity supply. This is wireless and the weird part is that it works on the same frequency as the p38 RF receiver found in the boot of the car. 433mhz. Clearly the alarm RF box in the car will need to be change for a newer model that is not affected by domestic wireless technology found in the home.. This can be bought for about 150 quid. The little light found on the console next to the gear stick on the automatic was illuminating and this confirms that wireless technology in my home was talking to the ecbm found under the drivers seat in the car. I understand that this can drain the battery over a few days as the ecbm shuts down, runs up, shuts down runs up etc.

Thanks to all for the help with regards to previous posts for flat battery and RF alarm issues.

have you taken the 'aerial' off the rf reciever, this may well stop the battery discharging whilst you obtain a new rf box. do a search(if you havnt already) and perform this trick to buy you some time!
