Change battery everything gone dead will not take land rover disc


Firstly, pop a new battery in the fob.
Now we can enter the EKA.
Close all the doors.
Turn the key in the driver door lock to the unlock position and hold there for at least 5 seconds until the alarm sounds once. Then return to centre - always ensure you return to centre and do not delay more than 10 seconds between turns, or hold in the position for more than 5 seconds or you will reset to the start. Turn to full extent of travel.
1st Digit turn to unlock the number of times specified.
2nd Digit turn to lock the number of times specified.
3rd Digit turn to unlock the number of times specified.
4th Digit turn to lock the number of times specified.
Finally turn to unlock once more. If it is correct a double bleep will sound (single bleep is incorrect code)
You now have a 5 minute delay - don't open any doors. The anti-theft indicator will continue flashing once every 2 seconds for the five minute period. When this goes out, open the door and start within 30secs.
After 3 failed attempts, the security system invokes a delay period of 10 mins during which the system will not accept any further attempts to enter a code.

How come on a 2002 GMC Denali if you lock your key inside


i would say the theft module saw the door trying to be open without the door lock or fob first, once the door lock button was pushed it shut down, it new doors were trying to be unlocked in a theft manner, once shut down it needs time to reset or needs to see ignition cycle with key and read chip in key, smart system isnt it, good luck.
