OPENING A STANDARD B.A.S.I.S. LOCK WITH DEAD BATTERIES
If you were not able to replace the batteries before they died in a
standard B.A.S.I.S. Lock and you cannot unlock the lock, you can
provide temporary power to the lock and use a valid card or PIN to
unlock it. Then, you can access the lock’s battery compartment to
replace the battery pack.
1. To provide temporary power to the lock, connect the programming
cable, with an external battery pack connected, to the lock’s
communication port. Although the serial cable and PDA do not need
to be connected to the programming cable, it will not cause a
problem if they are connected.
2. To unlock the lock, use a valid operating card for the lock.
3. Replace the lock’s battery pack. See page 11–4.
4. Disconnect the programming cable from the lock.
