Smart Lock Remote Battery Testing.

This document will explain the method to identify battery related problems with the "smart lock" remotes used from EBII - AU Falcons. Commonly battery related faults are actually a dirty/bad connection between the battery and the remote.

1. Remove the front cover from the smart lock remote by taking out the screw on the rear of the remote, and gently separating the covers.

2. Identify on the circuit board the main battery contacts, as shone below.

3. Place a multi-meter on these terminals, and while pressing either button on the remote, observe the reading. Anything over 10V is fine.
If at this point the voltage is 10V or more, the problem is a non battery related problem.

4. Placing the multi-meter leads directly on the battery terminals while the battery is still in the remote, repeat the previous procedure. If the Battery voltage is higher than shown at the terminals on the circuit board, and higher than 10V, the battery itself is not faulty, follow the following procedure.

If the battery reads similar to the previous step, replace the battery, And clean the terminals in the remote

5. To clean the terminals on the remote (where the battery goes) use a small flat bladed screwdriver and scrape the corrosion and dirt etc off the contacts.

6. Check to see if the battery fits securely in the remote. If the terminals do not securely hold the battery, simply bend one or both of them very gently towards the centre of the remote using a small flat screwdriver.

7. Refit the battery and check the voltages at the contacts on the remote circuit board, again while pressing a button on the remote. Compare the voltage to the voltage on the battery itself, again while pressing a button on the remote; it should be the same/very close.

8. Assuming the remote appears to work correctly, re-assemble the remote, and test on the vehicle. It should not be necessary to re-train the remote to the car.
