! Replacing lost transmitters
If you lose a transmitter or want to purchase additional
transmitters (up to four can be programmed), you
should re-program all of your transmitters for security
reasons. It is recommended that you have your dealer
program all of your transmitters into your system.
! Programming the transmitters
The keyless entry system is equipped with a special
code learning feature that allows you to program new
transmitter codes into the system or to delete old
ones. The system can learn up to four unique transmit-
ter codes. The four transmitter codes may be the
same or different.
