Step-by-Step DIY Repair Procedures

Thoroughly eliminate the old battery, noting the orientation (positive/negative side).
Place the brand-new battery and snap the casing back together.
Check the remote near the vehicle.

2. Cleaning Up Internal Contact Points

In time, dust, pocket lint, and skin oils can seep into the remote, developing a film over the circuit board contacts.

The Process:

Disassemble the remote shell.
Use a cotton bud dipped in a small quantity of isopropyl alcohol (70% or higher).
Gently clean the gold or copper contact pads on the circuit board and the conductive underside of the rubber buttons.
Allow the parts to air dry totally before reassembling.

3. Re-soldering Loose Components

For those with standard electronic devices experience, a common physical failure involves the battery terminal or a button switch breaking away from the circuit board due to a drop.

The Process:

Inspect the board under a magnifying glass for broken solder joints.
Utilize a fine-tip soldering iron to re-attach the loose component.
Make sure no “solder bridges” (additional solder touching 2 courses) are created, as this will trigger a brief circuit.

Understanding Reprogramming

In some cases the hardware is completely practical, but the remote has “forgotten” its connection to the automobile. This often occurs after a battery has actually been dead for a prolonged period or if external radio frequency interference has triggered a desynchronization.
