P0513 on 2015-2021 Dodge Challenger: Invalid Key Fixes & Causes

What's Unique About the 2015-2021 Dodge CHALLENGER

For this generation of Dodge Challenger, the P0513 code is often linked to the Wireless Ignition Node 🎬 Watch: Understanding P0513 causes and how to fix it. (WIN), also called the Keyless Ignition Node (KIN) or, in more recent models, the Radio Frequency Hub (RFH). Several Technical Service Bulletins (TSBs) indicate that software glitches can trigger this code, sometimes during specific actions like remote starting. [Bulletin #18-035-15 REV-B] These modules have been a known failure point across many Chrysler/Dodge/Jeep/Ram vehicles of this era, leading to a range of frustrating key-related symptoms. A Customer Satisfaction Notification (YA7) also details an RF-Hub software update to mitigate vehicle theft, which permanently locks the module from receiving future key programming without replacement.

Symptoms You May Notice

• Engine will not crank or start.
• Engine cranks but does not fire up.
• Red security light on the instrument cluster is flashing or solid.
• Check Engine Light is on.
• Key fob is not detected or 'Key FOB Not Detected' message on EVIC.

• Message on dash says 'Damaged Key'.

Most Likely Causes

1. Low or Dead Key Fob Battery 🔴 High Probability Key fobs constantly emit a low-power signal and batteries have a finite life. This is the simplest and most common cause, frequently discussed by owners.
   How to confirm: Try using your spare key fob. If the car starts, the issue is with the primary key fob. You can also try the 'limp-home' feature: place the nose of the problematic fob directly on the start button and try to start the car. If it starts, the battery is almost certainly the culprit. Replacing the CR2032 battery is an inexpensive test.
   Typical fix: Replace the CR2032 battery inside the key fob.
   Est. part cost: $1-$5
2. Faulty Key Fob 🟡 Medium Probability The internal transponder chip or circuitry can be damaged from being dropped or from water exposure. Sometimes the solder joint for the battery holder breaks internally.
   How to confirm: If a new battery doesn't solve the issue and the spare key works, the original key fob is likely defective. A locksmith or dealer can test the fob's signal. Sometimes after a battery change, the fob acts erratically, displaying 'Damaged Key' messages.
   Typical fix: Replace and program a new key fob. This must be done by a dealer or a qualified automotive locksmith with the proper tools and the vehicle's PIN code.
   Est. part cost: $150-$400
3. Wireless Ignition Node (WIN/KIN/RFH) Failure 🟡 Medium Probability The WIN module (or newer RF Hub) is a known weak point on many Dodge/Chrysler products from this era, leading to various ignition and security faults. Internal components fail, preventing communication with the key.
   How to confirm: Symptoms include the key getting stuck, not turning, or intermittent no-start conditions even with a good key. Diagnosis requires a professional scan tool to check for communication errors with the module. If neither key works and their batteries are good, the module is the primary suspect.
   Typical fix: The WIN/RFH module must be replaced and programmed, or the original unit can be sent out for repair to avoid reprogramming costs.
   Est. part cost: $200-$600
4. PCM Software Glitch ⚪ Low Probability TSBs confirm that software issues can cause a P0513 code, sometimes after a PCM flash or under specific conditions like remote start. [Bulletin #S2208000073, #18-035-15 REV-B]
   How to confirm: A Dodge dealership can check if your vehicle's PCM has the latest software updates available by checking your VIN against their service records. Customer Satisfaction Notification YA7 also involves a PCM and RF-Hub update.
   Typical fix: Update the PCM software to the latest version. TSB S2208000073 specifically calls out performing the 'PCM REPLACED PROCEDURE' to re-establish the security handshake.
   Est. part cost: $0-$200

Rare But Worth Checking

• Faulty Powertrain Control Module (PCM): While rare, a failure within the PCM's immobilizer circuit can prevent it from recognizing a valid key. This is usually a last resort after all other components have been verified. TSB S2208000073 details the procedure for when this happens after a PCM replacement.
• Wiring Harness Issue: A damaged or corroded wire between the WIN/RFH module and the PCM can disrupt the security signal, leading to the code. This is uncommon but possible, especially if other electrical work has been performed or if there was water intrusion. A wiring diagram is needed for diagnosis.
• Radio Frequency Interference: In rare cases, strong radio frequency interference from aftermarket devices or even other RFID-blocking items in a wallet or purse can prevent the key from being read correctly. An owner on Reddit noted that HID work badges can interfere with the key signal.

Diagnosis Steps

1. Check for a Check Engine Light and a flashing security indicator on the dashboard.
2. Try to start the vehicle with your spare key fob. If it works, the problem is isolated to your primary key.
3. If the primary key fails, attempt to start the car by pushing the start/stop button directly with the nose of the key fob. If this works, it strongly indicates a weak key fob battery.
4. Replace the battery (CR2032) in the non-working key fob. This is a cheap and easy first step.
5. If a new battery does not fix the issue, the key fob itself may be damaged and require replacement and programming.
6. If the spare key also fails to start the car, the problem is likely with the vehicle's receiver system (WIN/RFH).
7. Check for any available Technical Service Bulletins (TSBs) or Customer Satisfaction Notifications (like YA7) related to P0513 or the RF-Hub module for your specific vehicle. A dealer can perform any necessary software updates. [30, Bulletin #S2208000073]
8. Using an advanced scan tool (like wiTECH or AlfaOBD), a technician should check for communication with the Radio Frequency Hub (RFH) / Wireless Control Module (WCM).
9. Inspect the wiring and connectors at the RFH module for any signs of damage or corrosion. The RFH communicates over a CAN bus, so checking these wires is critical.
10. If the RFH module is suspected, it will need to be tested and likely replaced and programmed by a professional, or sent to a mail-in repair service. This requires the vehicle's 4-digit PIN.

• 18-035-15 REV-B: Details a specific scenario where P0513 is set during remote start if the key fob is pressed against the ignition node simultaneously.

Platform-Specific Known Issues

• A known software glitch can set P0513 during a remote start attempt if a key fob button is pressed against the ignition node at the same time. [Bulletin #18-035-15 REV-B]
• Replacing or flashing the PCM can sometimes lead to this code if the security keys are not properly relearned by the system. A specific 'PCM Replaced Procedure' must be run with a dealer tool to fix this handshake issue. [3, Bulletin #S2208000073]

Scan Tool Commands That Help

• wiTECH (Dealer Tool): WIN Replaced / PCM Replaced — This function, found in the Wireless Control Module (WCM) section, is mandatory after replacing the RF Hub or PCM. It programs the vehicle's secret key ID into the new module and requires the vehicle's 4-digit PIN.
• wiTECH (Dealer Tool): Programming Ignition Keys or Key Fobs — Used to add new keys to the vehicle's security system. This also requires the 4-digit PIN to enter the secure access mode.
• AlfaOBD (Advanced DIY): Program Ignition FOBIKs Baseline/Highline System — This function in the Radio Frequency Hub (RFH) menu allows users to program new keys. It requires connecting to the RFH, reading the PIN, and then running the programming routine with the new key in the ignition.
• AlfaOBD (Advanced DIY): Read PIN — A critical first step before attempting any security programming. This function, under the Radio Frequency Hub (RFH) active diagnostics, retrieves the vehicle's secret 4-digit PIN needed to authorize key and module programming.

Wiring & Ground Locations

• Radio Frequency Hub (RFH) Module — On 2015+ Challengers, the RF Hub is typically located in the trunk, on the right rear side, behind the trim paneling.. This module is the brain of the immobilizer system. All communication from the key fob goes through it. Diagnosing P0513 often requires physical access to this module to check its connections or replace it.
• RF Hub CAN Bus Wiring — The RF Hub communicates with the PCM and BCM via the CAN bus. On the module's connector A, the CAN-C High wire is typically on pin 13 and CAN-C Low is on pin 14.. A wiring failure on this data bus will sever communication between the security module and the engine controller, directly causing a P0513 and a no-start condition. A technician would test for continuity and proper voltage on these pins.

Real Owner Repair Stories

• Reddit user in /r/Challenger (2016 Dodge Challenger Hellcat) — No-start condition after installing a new ECU. The RF Hub module VIN was showing all zeros and keys were erased.
  ❌ Tried (didn't work) Using CDA6 software to change the VIN in the ABS and BCM modules., Attempting to program keys back using an Autel IM608 Pro II after accidentally erasing the RF Hub's EEPROM data.
  ✅ What actually fixed it The user's post indicates the problem was caused by erasing the RF Hub's EEPROM, which bricked the module. The implied fix is the replacement of the RF Hub module itself, as programming became impossible once the VIN and key data were wiped.
• YouTube video on a sister platform (Jeep) (Jeep Wrangler (similar Chrysler immobilizer system)) — No-start, no-crank, with a solid red security light on the dash, and code P0513 active.
  ❌ Tried (didn't work) The video presents this as a get-you-home trick, not a permanent repair.
  ✅ What actually fixed it As a temporary bypass to get the vehicle started, the user pulled fuse M13 from the engine bay fuse box for a few seconds and then reinserted it. This allowed the engine to start, but it does not fix the underlying key communication issue.

OEM Part Supersession History

• Multiple (e.g., 5026298AD, 68064790AC, 68066725AB) → Mopar 68210151AB — Standard part evolution for the WIN (Wireless Ignition Node) module used in earlier models of the generation.
  Heads up: This part number trail refers to the older WIN-style module. Later vehicles use a different RF Hub. Always verify by VIN.
• 68283458AB → 68283458AC — Revision update for the RF Hub used in 2016-2017 models, specifically noted for high-performance engines (6.2L/6.4L).
• N/A → 68441616AA — This is a common RF Hub part number for later models in the generation (approx. 2019-2022).
  Heads up: Illustrates the part change in later years; not backward compatible with early-generation vehicles that used a WIN module.

Model Year Variations Within This Range

• 2015-~2017: Early models in this range may use the older Wireless Ignition Node (WIN) module, which is a single unit combining the ignition switch and receiver.
• ~2017-2021: Later models transitioned to a separate Radio Frequency Hub (RFH) module (located in the trunk) and a keyless push-button start system. While the function is similar, the parts and locations are completely different.
