The Dodge Charger comes equipped with Chrysler’s Sentry Key Immobilizer System (SKIS), which uses a key fob with a transponder chip that communicates with the vehicle’s Powertrain Control Module (PCM). If the wrong signal is received, the engine won’t start or will stall immediately. While this protects the Charger from theft, it can sometimes malfunction and prevent the rightful owner from starting the car. If your Charger cranks but won’t start, stalls quickly, or the security light flashes or stays on, you may need to reset the anti-theft system.
The good news is that in many cases, you can reset the system yourself without visiting a dealership. This guide explains why the Dodge Charger’s anti-theft system activates, step-by-step reset methods, recommended tools, and answers to common questions from Charger owners.

Buyer’s Guide: Why the Dodge Charger Anti-Theft System Activates
Your Charger’s Sentry Key system may activate and prevent the car from starting for several reasons:
- Weak or Dead Battery: Low voltage can cause the PCM to lose communication with the key fob.
- Faulty Key Fob: The transponder chip inside may be damaged or out of sync.
- Ignition Switch Issues: A failing ignition module may not read the key signal correctly.
- Blown Fuse: A failed ignition or security fuse can disable the immobilizer.
- Electronic Glitches: After a jump-start, battery replacement, or voltage spike, the SKIS may need a reset.
Step-by-Step Methods to Reset the Dodge Charger Anti-Theft System
Method 1: Key Fob Reset
- Press the unlock button on your key fob.
- Insert the key into the ignition and turn it to the ON/RUN position (engine off).
- Wait about 10 seconds, then turn the key back to OFF.
- Attempt to start the Charger.
Method 2: The 10-Minute Reset
- Insert the ignition key and turn it to the ON position without starting.
- Leave it for 10 minutes until the security light turns off.
- Turn the key OFF, then attempt to start the engine.
Method 3: Battery Disconnect Reset
- Turn off the ignition and remove the key.
- Disconnect the negative battery cable first, then the positive.
- Wait 10–15 minutes to clear stored signals.
- Reconnect the positive cable first, then the negative.
- Attempt to restart the Charger.
Method 4: Fuse Reset
- Locate the security/PCM fuse in the fuse box.
- Remove it for a few minutes, then reinstall it.
- Try starting the Charger again.
Method 5: OBDII Scanner Reset
- Plug a diagnostic scanner into the OBDII port under the dashboard.
- Select Dodge Charger and access the Sentry Key Immobilizer System (SKIS).
- Perform a “Security Relearn” or “Key Reset.”
- Clear stored immobilizer codes and restart the engine.

Frequently Asked Questions
Why is my Dodge Charger’s security light flashing?
This indicates the Sentry Key system does not recognise your ignition key or fob. Causes include a weak battery, faulty key chip, or PCM issue.
Will disconnecting the battery reset the anti-theft system?
It can help, but the 10-minute reset or key relearn methods are more reliable.
What if my Charger still won’t start after a reset?
You may have a failing ignition switch, damaged key fob, or PCM/BCM fault that requires service.
Can I bypass the anti-theft system permanently?
Bypass kits exist but compromise vehicle security. Resetting or repairing the system is the safer solution.
When should I see a dealer?
If manual resets and scanner resets don’t work, a Dodge dealer may need to reprogram your PCM or provide a new key fob.
Conclusion
The Dodge Charger’s Sentry Key system is a robust theft deterrent but can sometimes malfunction and lock out the owner. Fortunately, most issues can be resolved with the key fob reset, 10-minute reset, battery disconnect, or fuse reset. For persistent cases, an OBDII scanner with Chrysler/Dodge support provides dealer-level troubleshooting. In rare situations, a Dodge dealership may need to reprogram or replace system components.
Final tip: Keep your Charger’s battery healthy, maintain spare key fobs, and know these reset methods so you’ll always be prepared if the anti-theft system malfunctions.
