sorry for the delay............
Greetings...... “Hi, I’m Don (akaCustomer and I look forward to helping you!”
No one "deceived you"..........
It is likely that there was no Chrysler Expert On at that time..........
Very sorry for the wait.........
There is NO "disconnect switch" on your Chrysler 300 "unless" you have Aftermarket or Dealer Installed Alarm
Factory Alarm only DisArms like this:
Since this model is not equipped with lock cylinder switches, passive disarming of the VTSS is only possible if the vehicle is equipped with the optional Sentry Key Immobilizer System (SKIS).
On vehicles with SKIS, turning the ignition switch to the On position using a valid SKIS key will passively disarm VTSS.
Active disarming of the VTSS occurs when the vehicle is unlocked by depressing the "Unlock" button of the RKE transmitter.
Once the alarm has been activated, either disarming method will also deactivate the alarm.
Depressing the "Panic" button on the RKE transmitter will not disarm the VTSS.
IF you do NOT have Factory Alarm, please post the Brand & Model Number so I can help further........
