Step 4: Replace the Battery

Using a screwdriver, remove the cover or panel of your Yale lock to access the battery compartment. If there are any screws holding the cover in place, be sure to keep them safe for reassembly later.

Next, carefully remove the old battery and replace it with the new one. Make sure to align the positive and negative ends correctly according to the indications in the battery compartment.
