2001 X5 10 min timer not counting down

[TASTAB]

Can anyone help me PLEASE

Hi I got locked out of my X5 Yesterday, I got in the hood and hooked up a starter Pack and got the thing open.

Asking for code I have tried 0000 to no avail.
Got this out of the book and get to the of the count down but the clock stays at 9:59

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.
