Transmitter

The installation process for the Keyless Entry Transmitter with Smart Key System begins with positioning a new lithium battery having the positive (+) side orientation facing upward and pressing it gently to lock it into place. Correct positioning of the positive (+) and negative sides of the transmitter battery requires special attention when performing installation while avoiding any bending of battery terminals. The interior of the transmitter case must stay free of dust together with water and oil. Proceed with using the mechanical key to place the cover after securing the battery into position. Pressing any transmitter switch should turn on the built-in LED to confirm the setup was successful after the installation is complete.

A person needs to extract the mechanical key before proceeding to remove the Keyless Entry Transmitter with Smart Key System. First, create a gap using a screwdriver that you should tape for protection before using the tool to detatch the cover by turning it. You should remove the lithium battery using a screwdriver while taking caution to prevent manually touching the terminals or forcefully lifting the battery which could deform its shape. Contacting the battery with moist hands should be avoided to stop corrosion from forming while you must refrain from handling interior transmitter pieces to protect its correct functioning.

First, take special caution when handling each component as they are precision electronic components.
