wArning: Door LoCK SYnCHroniZATion
IMPORTANT
I
The door lock signal is encrypted on select models. In order for the bypass to operate properly, it must be synchronized with that encrypted
signal. However, when the vehicle is driven, data is sent along the bus that desynchronizes the bypass with the encryption.
To regain synchronization once the engine is shut off, the bypass must see the factory keyless codes (OEM remote or proximity lock/unlock
codes). This solution will resynchronize automatically upon seeing the fi rst factory keyless code and will operate normally (both convenience and
immobilizer bypass/remote starter functionality).
Conversely, if the vehicle is driven and the factory keyless system is not used to lock or unlock, the aftermarket remote will not be able to lock or
unlock until the bypass receives factory keyless code at least once as described above.
If one does not intend to use factory keyless after driving the vehicle, additional wiring is required to ensure the bypass remains synchronized
with the encryption. Remote starter door locks must be hardwired (see wiring diagram). This will permit lock/unlock with the aftermarket re-
mote at all times without necessitating the use of the factory keyless system.
Please note that this fi rmware also supports “External Remote Control Arm and Disarm” which means that the bypass can arm and disarm the
aftermarket alarm using OEM Keyless when paired with most popular remote starter brands. When used exclusively in this manner (i.e. without
aftermarket remote controls), hardwired remote starter door locks (as described above) become unnecessary.
Finally, as factory keyless operates normally during remote start with this solution and take-over is not supported, a one-button remote control
is a very good choice for these vehicles in order to prevent any possible user issues.
