Big problem ! please help asap

[idayekh]

I got a big problem, every evening i put my start code on the control panel of my x5, this morning when i tried to start the car with my code, it didn't work, he didn''t accept the code i used ( wich is the correct one ) and after couple tries the alarm went off. afterwords i checked the users manual and there's an way to go past this, i'll write here what is written in the users manual ;

After three incorrect code entries, or
three attempts to start the engine
without a code entry, the alarm will
sound for 30 seconds on vehicles fitted
with an alarm system.
Deactivating the alarm in an
emergency:
If you have forgotten the code, proceed
as follows:
1. Disconnect the battery, wait approx.
2 minutes, then reconnect it. Note
that on vehicles with an alarm
system, the alarm will sound
2. Set the ignition key to position 1:
The time display will count down for
the next ten minutes

3. After ten minutes, start the engine.

So i did all this and the engine works fine now, but the problem is my remote key locking doesn't work anymore, my alarm is also out of working order, and the interier light only front one doesn't work. but if i press the buttom to open the trunk, it works, but doors don't open/ close. Anyone has a problem like this before or can tell me where to look , ... ? i checked the fuses underneath the gloves department and there all good. ( the ones that work for the key locking. so i hope you guys can help because in 2 days i leave for holliday and i hope i can solve it. thanks in advance.
