2008 Chevrolet Uplander Transponder Key B99PT PK3

This is a PK3 transponder key with the keyway groove on the right side of the keyblade (B99-PT.) Have a local locksmith cut the key to work your vehicle and then you can perform the procedure below to add the key to your car’s computer.

If you have one working transponder key:
1. Switch ignition to ON with master key.
2. Switch ignition to OFF and remove key.
3. Within 10 seconds insert new key.
4. Switch ignition to ON. New key should now be programmed.

If you have no working transponder key:
1. Make sure the vehicle’s battery is fully charged. Put key in ignition and crank engine for a fraction of a second and leave the key in the ON position for exactly 10 minutes.
2. Turn OFF and remove key.
3. Put key in ignition and crank engine for a fraction of a second and leave the key in the ON position for exactly 10 minutes.
4. Turn OFF and remove key.
5. Put key in ignition and crank engine for a fraction of a second and leave the key in the ON position for exactly 10 minutes.
6. Turn OFF and remove key. New key should now be programmed.

Troubleshooting:
– If the first procedure is not working then when it says to turn ignition to ON, instead go further and crank the engine for a moment but not long enough that the engine starts.
– If the above procedures seem to work but then the key only works for a minute then clean the key blade with alcohol and a brush (like brillo or steel wool.)
– If you are doing the first procedure make sure you put the old key first. If you put the new key first you can either cancel the procedure or on some models cancel the first key.
– The car battery has to be in charged well before you begin. If the car battery is weak it can cancel the procedure or on some models cancel a working key.
