Getting To Know Your Vehicle -> Sentry Key for Your Fiat 500 L 4 Door First Generation (2012-2022)

20 GETTING TO KNOW YOUR VEHICLE  
Key-In-Ignition Reminder  
CAUTION!  
Opening the driver’s door when the key is in the ignition  
and the ignition switch position is in the OFF/LOCK  
position, a signal sounds to remove the key.  
Always remove the Sentry Key from the vehicle and  
lock all doors when leaving the vehicle unattended.  
The Sentry Key Immobilizer system is not compat-  
ible with some aftermarket remote starting systems.  
Use of these systems may result in vehicle starting  
problems and loss of security protection.  
SENTRY KEY  
The Sentry Key Immobilizer System prevents unauthor-  
ized vehicle operation by disabling the vehicle. The system  
does not need to be armed or activated. Operation is  
automatic, regardless of whether the vehicle is locked or  
unlocked.  
All of the keys provided with your new vehicle have been  
programmed to the vehicle electronics.  
Key Programming  
The system uses ignition keys which have an embedded  
electronic chip (transponder) to prevent unauthorized ve-  
hicle operation. Therefore, only keys that are programmed  
to the vehicle can be used to start and operate the vehicle.  
Programming key fobs may be performed at an authorized  
dealer.  
Replacement Keys  
NOTE: A key which has not been programmed is also  
considered an invalid key, even if it is cut to fit the ignition  
switch lock cylinder for that vehicle.  
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. When having the Sen-  
try Key Immobilizer System serviced, bring all vehicle  
keys with you to an authorized dealer.  
If the vehicle security light is on after the key is turned to  
the MAR (ACC/ON/RUN) position, it indicates that there  
is a problem with the electronics.

1. This device may not cause harmful interference, and  
3. The horn will sound and the vehicle security light in the  
instrument cluster will switch on for approximately  
three seconds. This shows that the vehicle security  
alarm is about to arm. During this period, if a door is  
opened, the ignition switch is turned to ON/RUN, or  
the power door locks are unlocked in any manner, the  
vehicle security alarm will automatically disarm. After  
approximately three seconds, the vehicle security light  
will flash. This shows that the vehicle security alarm is  
fully armed.  
2. This device must accept any interference received, includ-  
ing interference that may cause undesired operation.  
NOTE: Changes or modifications not expressly approved  
by the party responsible for compliance could void the  
user’s authority to operate the equipment.  
VEHICLE SECURITY ALARM  
The vehicle security alarm monitors the vehicle doors for  
unauthorized entry and the ignition switch for unauthor-  
ized operation. While the vehicle security alarm is armed,  
interior switches for door locks and liftgate release are  
disabled. If something triggers the alarm, the vehicle  
security alarm will provide the following audible and  
visible signals: the horn will pulse, the park lamps and/or  
turn signals will flash, and the vehicle security light on the  
instrument panel will flash.  
The activation of the vehicle security alarm is followed by  
a self-diagnosis stage. If a fault is detected during the  
self-diagnosis stage, the horn will sound a second time.  
If the horn sounds a second time, check that all doors, hood  
and liftgate are closed correctly, then rearm the system.
