Dodge 2004 Ram SRT-10 - Manual (Page 12)

The
ЉSecurity LightЉ, located in the instrument cluster,
will illuminate for about 2 seconds when the ignition
switch is first turned to the ON position. If the vehicle
electronics do not receive a valid signal from the ignition
key, the
ЉSecurity LightЉ will flash continuously to signal
that the vehicle has been immobilized. If the ЉSecurity
Light
Љ remains on during vehicle operation, it indicates a
fault in the system electronics. If this option was ordered,
all of the keys provided with your new vehicle have been
programmed to the vehicle electronics.
Replacement Keys
NOTE: Only keys that have been programmed to the
vehicle electronics can be used to start the vehicle. Once
a Sentry Key has been programmed to a vehicle, it cannot
be programmed to any other vehicle.
At the time of purchase, the original owner is provided
with a four digit PIN number. This number is required
for dealer replacement of keys. Duplication of keys may
be performed at an authorized dealer or by using the
Customer Key Programming procedure. This procedure
consists of programming a blank key to the vehicle
electronics. A blank key is one which has never been
programmed and needs to be cut.
NOTE: When having the Sentry Key System serviced,
bring all vehicle keys to the dealer.
