Am I able to get a key for programming the till as the ones we had have been misplaced.only have keys to turn on the till and service other funcions apart from the programm ?

Press the unlock button on your vehicle's key fob to deactivate the alarm.

If you've misplaced your remote for the car, use the PATS programmed key to unlock the driver's side door.

Then, put the key in the ignition and turn the key to the "on" position. The vehicle's battery should be on, but the engine shouldn't be running.

Locate the override button on the alarm box, beneath the driver's side of the dashboard.

Press the button and hold it in until the alarm beeps one time. The LED light for the alarm should stop blinking, indicating the anti-theft system is disabled.

To reset the vehicle's alarm, put the PATS programmed key in the ignition and turn the key to the "on" position. Press the override button.

When the alarm resets, it chirps two times and the LED light begins blinking.

Can I program a second key myself if I have one working key?
No, here are your options.
1. Preferred Option: Call or go to an Automotive Locksmith and they will have to
connect a special computer to your vehicle to program the second key.

2. Go to a Dealership and they will have to connect a special computer to your
vehicle to program the second key.

if all you want to do is clear all totals, turn the program key to off. hold down the RECEIPT FEED button and turn the key to PROGRAM. release the button and now you should see a line of F's. enter 8888888888 and press subtotal. this will clear all the totals and leave the program intact.

The Customer Learn programming method procedures are as follows:

1. Obtain the blank Sentry Key(s) that are to be programmed as valid keys for the vehicle. Cut the blank key(s) to match the ignition switch lock cylinder mechanical key codes.

2. Insert one of the two valid Sentry Keys into the ignition switch and turn the ignition switch to the ON position.

3. After the ignition switch has been in the ON position for longer than 3 seconds, but no more than 15 seconds, cycle the ignition switch back to the OFF position. Replace the first valid Sentry Key in the ignition switch lock cylinder with the second valid Sentry Key and turn the ignition switch back to the ON position. The second valid Sentry Key must be inserted in the lock cylinder within 15 seconds of removing the first valid key.

4. About 10 seconds after the completion of Step #3 , the security indicator in the instrument cluster will start to flash and a single audible chime will sound to indicate that the system has entered the Customer Learn programming mode.

5. Within 60 seconds of entering the Customer Learn programming mode, turn the ignition switch to the OFF position, replace the valid Sentry Key with a blank Sentry Key transponder, and turn the ignition switch back to the ON position.

6. About 10 seconds after the completion of Step #5 , a single audible chime will sound and the security indicator will stop flashing, stay ON solid for 3 seconds, then turn OFF to indicate that the blank Sentry Key has been successfully programmed. The SKIS will immediately exit the Customer Learn programming mode. After the ignition is cycled the vehicle may be started using the newly programmed valid Sentry Key.

Each of these steps must be repeated and completed in their entirety for each additional Sentry Key that is to be programmed. If the above steps are not completed in the given sequence, or within the allotted time, the SKIS will exit the Customer Learn programming mode and the programming will be unsuccessful. The SKREEM will also automatically exit the Customer Learn programming mode if it sees a non-blank Sentry Key transponder when it should see a blank, if it has already programmed 8 valid Sentry Keys, or if the ignition switch is turned to the OFF position for more than about 50 seconds.

Turn on ignition. Press soft key (6) (Set) on front panel to display setup menu. Press hrs+ soft key & hold till correct; repeat with min+ key.
