7.4 Key Programming Mode
Once the ESS has been placed into key programming mode the ESS will behave as if in āsleep modeā for one ig nition cycle
only. This allows for the one ignition cycle that is required to program a new key to a new or existing BCM. The ESS will
enter ānormal modeā for the next ignition c ycle. If the BCM is a new BCM in the vehicle with a new security code, the ESS
will then enter āarmed modeā as expected.
Programming Extra Keys To The Vehicle
Programming more keys for the vehicle can be achieved using TECH 2 once the ESS has been re-linked to the vehicle as
described as follows:
1. Ensure all doors, boot and bonnet ar e close d, all doors are unlock ed, dome lamp is in the ādoors ā pos ition and the ra dio,
headlight and wash-wipe switches are off.
2. Place new key into the ignition barrel.
3. Turn ignition on. Verify ESS beeps 5 times.
4. For VT.II / VX Vehicles TECH 2 must be operating in the āNormal Modeā submenu of the Body Control Module sub-
menu.
For VY / WK / Coupe III Vehicles TECH 2 must be operating in the Body Control Module sub-menu only.
5. Perform the Link Enable Procedure (see S ection 7.5). Wait 1 second bet ween each lock unlock to e nsure the door lo ck
actuators function correctly during this procedure.
6. Verify that the ESS beeps twice. TECH 2 reports ignition is at 12V DC. The ESS has now entered āKey Programming
modeā.
7. Select Key Programming function ā āExtra Keyā - from the security sub-menu in the body menu of the TECH 2. When
TECH 2 requests ignition to be c ycled with the existing ke y, leave the new key in the ignition barre l and instead, press
the unlock button on the existing key. Verify the ESS beeps once and the Theft Deterrent LED stops flashing.
Complete key programmin g a s requested by TECH 2.
8. Turn ignition off and wait for 2 seconds.
1. Once and the Theft Deterrent LED stops flashing. Complete key programming as requested b y TECH 2.
2. Turn ignition off and wait for 2 seconds.
3. Turn ignition on. Verify ESS beeps once. The ESS is now operating in ānormal mod eā
4. Crank engine. Verify vehic le starts as normal.
9. Turn ignition on. Verify ESS beeps once. The ESS is now operating in ānormal modeā.
10. Crank engine. Verif y vehicle starts as normal.
Programming All New Key
Programming an All New Key for the vehicle can be achieved b y performing the following procedure:
1. Ensure all doors, boot and bonnet ar e close d, all doors are unlock ed, dome lamp is in the ādoors ā pos ition and the ra dio,
headlight and wash-wipe switches are off.
2. Place new key into the ignition barrel.
3. Turn ignition on. Verify ESS beeps 5 times.
4. For VT.II / VX Vehicles TECH 2 must be operating in the āNormal Modeā submenu of the Body Control Module sub-
menu.
For VY / WK Vehicles TECH 2 must be oper ating in the Body Control Module sub-menu.
5. Perform the Link Enable Procedure (see Section 7.5). Wait 1 second bet ween each lock unlock to e nsure the door lo ck
actuators function correctly during this procedure.
6. Verify that the ESS beeps twice. TECH 2 reports ignition is at 12V DC. The ESS has now entered āKey Programming
modeā.
7. Select Key Programming function ā āAll New Keyā - from the securit y sub-menu in the bo dy menu of the TECH 2. Enter
BCM security code as requested by TECH 2. Complete key programming as requested b y T E CH 2.
8. Turn ignition off and wait for 2 seconds.
9. Turn ignition on. Verify ESS beeps once and Theft Deterrent LED is off. The ESS is now operating in ānormal modeā.
10. Crank engine. Verif y vehic le starts as normal.
