P0513 on 2015-2021 Dodge Charger: Invalid Key & No-Start Causes

What's Unique About the 2015-2021 Dodge CHARGER

On the 2015-2021 Dodge Charger, the P0513 code is often linked to the specific behavior of its Keyless Enter-N-Go system. A manufacturer Technical Service Bulletin (TSB #18-035-15 REV-B) highlights a scenario where the code can be set by using the remote start and then immediately pressing the key fob against the start button. This indicates a sensitivity in the system's logic. Other TSBs show this code can appear after a PCM software update or replacement, requiring a specific 'RF Hub Replace' relearn procedure using a dealership's wiTECH diagnostic tool. A significant number of owner reports point to the RF Hub module itself as a common failure point, leading to a P0513 even with known-good keys.

Most Likely Causes

1. Weak or Dead Key Fob Battery 🔴 High Probability Key fobs for this generation use a CR2032 battery which has a finite life. A weak battery may not provide a strong enough signal for the car's RF Hub antenna to read, especially in cold weather.
   How to confirm: Try your spare key fob. If the car starts, the issue is with the first key. You can also try placing the 'nose' of the non-working fob directly against the start/stop button and pushing the button with the fob itself; this can sometimes allow the low-power signal to be read. If this works, the fob battery is almost certainly the cause.
   Typical fix: Replace the CR2032 battery inside the key fob. 🎬 Watch: How to replace your key fob battery in minutes.
   Est. part cost: $1-$5
2. Faulty RF Hub (WCM) 🔴 High Probability Forum discussions and owner complaints indicate the RF Hub module, located behind the rear seat side bolster, 🎬 See this walkthrough on how to access the RF Hub. is a common failure point on this platform. It can fail internally, preventing it from recognizing any programmed keys.
   How to confirm: If both key fobs (even with new batteries) fail to start the car, and the 'push the fob to the button' trick doesn't work, the RF Hub is a prime suspect. A professional diagnosis with a tool like wiTECH is needed to confirm if the module is unresponsive.
   Typical fix: The RF Hub module must be replaced, and the new module must be programmed to the vehicle's VIN. All existing keys must then be re-programmed to the new hub. This is typically a dealer-only repair.
   Est. part cost: $150-$300 for the part, but the total dealer bill is often reported to be $800-$1200 including labor and programming.
3. Faulty Key Fob 🟡 Medium Probability Key fobs can be damaged by being dropped or exposed to moisture, causing the internal transponder chip to fail.
   How to confirm: If a new battery doesn't solve the issue and the spare key works perfectly, the original key fob is likely defective. A locksmith's tool can also test the transponder output directly.
   Typical fix: The key fob must be replaced and programmed to the vehicle by a dealer or qualified locksmith.
   Est. part cost: $150-$400 for an OEM key and programming.
4. PCM/BCM Software Glitch 🟡 Medium Probability Multiple TSBs (#18-061-17, #18-047-16) indicate that P0513 can be stored along with other unrelated codes, and the prescribed fix is a PCM software update. This suggests software logic errors can incorrectly trigger the code.
   How to confirm: A dealership or properly equipped shop must check the current software calibration of the PCM and compare it against the latest available version using their database.
   Typical fix: Update the Powertrain Control Module (PCM) software to the latest version.
   Est. part cost: $0 (if part of a warranty or recall), or 1-2 hours of labor cost for flashing.
5. Incorrect Key Programming ⚪ Low Probability This occurs after a PCM is replaced or flashed, or if an aftermarket key was programmed incorrectly. TSB #S2208000073 specifically calls out a no-start with P0513 after PCM replacement due to an invalid SKIM key setting that requires a 'Restore Vehicle Configuration' procedure.
   How to confirm: This is typically diagnosed after a recent repair involving the PCM or keys. The vehicle will not start, and a scan tool will show the P0513 code.
   Typical fix: The keys must be re-programmed to the vehicle's immobilizer system using a dealership diagnostic tool (wiTECH).
   Est. part cost: $0 (parts), but labor will apply.

Rare But Worth Checking

• Low Main Vehicle Battery Voltage: A weak or dying 12V vehicle battery can cause a multitude of electronic issues, including communication errors between modules. The RF Hub may not receive enough power to operate correctly, leading to a P0513 code even if the key and hub are fine. A diagnostic code can be set in the RF Hub if system voltage drops below 10.0 volts.
• Wiring Issue: A damaged wire or poor connection in the circuit between the RF Hub and the PCM can interrupt the security signal and trigger the code. This is uncommon but can happen due to previous repairs, rodent damage, or chafing.
• External RF Interference: Rarely, strong radio frequency interference from other devices (like aftermarket alarm systems, 24-hour gym access cards on the keychain, or RF gate cards) can disrupt the signal between the key fob and the RF Hub.

Diagnosis Steps

1. Check for a "Key Not Detected" message or a flashing red security light on the dash.
2. If you have a spare key, try starting the vehicle with it. If it works, the problem is with the primary key fob.
3. Replace the battery (CR2032) in the non-working key fob. This is the most common and cheapest first step.
4. If the new battery doesn't help, try holding the nose of the key fob directly against the engine start button and pressing the button with the fob. If the car starts, it confirms a signal strength issue, but the fob's transponder is likely still good.
5. If the spare key also does not work, the problem is likely with the vehicle's security system (e.g., the RF Hub).
6. Check the main 12V vehicle battery's state of charge and health. Low voltage can cause module communication errors.
7. Check for any available Technical Service Bulletins (TSBs) related to P0513 for your vehicle. Several TSBs exist for software updates that resolve this code.
8. If no simple fix is apparent, the vehicle needs to be scanned with a professional tool that can access the immobilizer system (RF Hub/WCM).
9. A professional will need to diagnose the Wireless Control Module (WCM/RF Hub), its wiring, and potentially replace the module, reprogram the keys, or update the PCM software.

• Owner Experience: A very common failure scenario involves the RF Hub module failing. Owners report being able to unlock the doors and even remote start the car, but it shuts off when they press the start button to drive, accompanied by the P0513 code. The repair consistently involves towing the car to a dealer for an RF Hub replacement costing upwards of $1000.

Mechanic-Grade Diagnostic Values

• System Voltage at RF Hub — expected: Above 10.0 Volts. Failure: A code may be set in the RF Hub if the BCM reports system voltage is below 10.0 volts for more than 15 seconds. This can cause communication issues leading to P0513.

Hidden / Shadow Codes Worth Checking

• B1A25: Invalid Key. This code is stored in the security module (RF Hub) and directly relates to the key not being recognized. (see via A professional scan tool capable of reading Body Control Module (BCM) and security module DTCs.)
• B1A7D-01: Start Button - General Electrical Failure. This code can be stored in the RF Hub and may indicate an issue with the push-to-start button circuit, which is part of the key validation sequence. (see via A professional scan tool. This code is mentioned in a Technical Service Bulletin.)

Scan Tool Commands That Help

• wiTECH (Dealer Tool): Restore Vehicle Configuration — This function is required after replacing or re-flashing the PCM or RF Hub to install the correct security codes and vehicle options, resolving a P0513 set after a repair.
• wiTECH (Dealer Tool): PCM/ECM/ESL replace — Located under the BCM 'Miscellaneous Functions' menu, this routine transfers the immobilizer data to a newly installed PCM to establish the security handshake.
• wiTECH (Dealer Tool): Proxy Configuration Alignment — This is a mandatory final step after any module replacement or flash to ensure all modules on the CAN bus network are properly synchronized. Failure to do so can cause communication errors.
• AlfaOBD / Autel (Advanced Aftermarket): Program Key Fob / Read PIN — If the security PIN for the vehicle is known, these tools can program new keys. PIN reading may be blocked on 2018+ models, requiring a dealer to provide the PIN.

Wiring & Ground Locations

• RF Hub (RFH) Module — Located in the trunk, underneath the rear package shelf/tray, behind the rear seats. It is often behind the left rear cargo quarter trim panel.. This is the central module for the keyless entry and immobilizer system. All communication from the key fob goes through this module. Physical access is required for replacement, and its wiring is a potential point of failure.
• RF Hub Connector A — The main connector on the RF Hub module.. Pin A-13 is for CAN-C High (+) and Pin A-14 is for CAN-C Low (-). These are the primary communication lines to the PCM and BCM. A poor connection here will cause a P0513.

Real Owner Repair Stories

• YouTube user 'Lou Pimber' (2015 Dodge Charger) — Keyless entry and remote start worked, but pressing the start button resulted in a 'no key detected' message or the engine would start and immediately shut off. The immobilizer was activating.
  ❌ Tried (didn't work) The owner did not list other attempted fixes, but took the car to the dealership for diagnosis after the symptoms appeared.
  ✅ What actually fixed it The dealership diagnosed a failed RF Hub. The owner purchased a new RF Hub and replaced it himself, documenting the location and process. The final step required was to have the new module programmed to the vehicle.
• DodgeForum.com user (2018 Dodge Charger Daytona 392) — Needed to program a second key fob, but could not extract the security PIN using multiple advanced aftermarket scan tools.
  ❌ Tried (didn't work) Autel MS906BT could not pull PIN., Launch X431 PROS was unsuccessful., Chrysler PIN Puller app reported the RF Hub was 'blocked'.
  ✅ What actually fixed it The owner went to the dealership, who provided the vehicle's security PIN at no cost. Using the PIN, the owner was then able to successfully program the new key fob using the AlfaOBD software. This confirms a viable repair path for key-related P0513 issues.

OEM Part Supersession History

• 68441622AA → 68441622AB — Standard part revision by the manufacturer, likely for improved reliability or internal component changes.
  Heads up: The new part number (68441622AB) is the correct service replacement for the original. Using the old part number is not advised.

Model Year Variations Within This Range

• 2018-2021: The RF Hub on 2018 and newer models may have enhanced security ('blocked' or 'locked'), which prevents many aftermarket tools from being able to extract the vehicle's security PIN needed for key programming. On these models, it is more likely that the PIN must be obtained from a dealership.
