B3060 on 2007-2011 Pontiac Solstice: Understanding the No-Start Security Code

What's Unique About the 2007-2011 Pontiac SOLSTICE

The Pontiac Solstice uses GM's Passkey III+ (PK3+) immobilizer system, which is common across many GM vehicles of this era. The system is generally reliable but is known to be sensitive to interference. A GM Technical Service Bulletin highlights that other Radio Frequency (RFID) devices on the same keychain—like other car fobs, office access cards, or gas station payment fobs—can disrupt the signal between the Solstice key and the ignition, causing this code to appear intermittently. This is a very common point of failure for this specific platform and its sibling, the Saturn Sky.

Diagnostic Flowchart

Tap your situation to follow the diagnostic path that matches what you're seeing on this vehicle.

Symptoms You May Notice

• Engine will not crank or start.
• Engine starts briefly and then immediately stalls.
• The security indicator light (an icon of a car with a padlock) on the instrument cluster is illuminated or flashing.
• A single 'click' sound may be heard from the Body Control Module (BCM) area when turning the key, but the starter does not engage.

Most Likely Causes

1. Using a New or Unprogrammed Key 🔴 High Probability This is common after a key replacement or if a new key has been cut but not electronically programmed to the car's TDM.
   How to confirm: This is the cause if you are attempting to use a newly cut key that has not been through the vehicle's key relearn procedure.
   Typical fix: The new key must be programmed to the vehicle using the 30-minute key relearn procedure. 🎬 Watch: A step-by-step guide to programming your new transponder key. In some cases, a locksmith or dealer with a Tech 2 scan tool may be required.
   Est. part cost: $0 if performing relearn, $50-$150 for locksmith/dealer programming.
2. Radio Frequency (RF) Interference 🟡 Medium Probability As noted in GM TSB #PIC5650M, the Passkey system can be sensitive to other RFID devices. This is a widely reported issue on Solstice and Saturn Sky forums.
   How to confirm: Remove all other keys, fobs, and access cards from the keychain. Try starting the vehicle with only the Solstice key present. If the car starts, interference was the issue.
   Typical fix: Keep other RFID-emitting devices separate from the vehicle key when starting the car. This is a behavioral fix, not a mechanical one.
   Est. part cost: $0
3. Faulty Ignition Key Transponder 🟡 Medium Probability The transponder chip embedded in the key head can be damaged from being dropped or from age. This is a common failure point.
   How to confirm: Try starting the vehicle with a spare, known-good key. If the spare key works and the primary key does not, the primary key's transponder is faulty.
   Typical fix: Replace the faulty key and program the new one to the vehicle using the 30-minute relearn procedure.
   Est. part cost: $40-$100 for a new key blank, plus programming costs if unable to perform the relearn procedure.
4. Faulty Ignition Lock Cylinder / Reader Coil ⚪ Low Probability The exciter ring/reader coil that surrounds the ignition cylinder can fail, preventing it from energizing and reading the key's transponder chip.
   How to confirm: If multiple known-good keys fail to start the vehicle and the 30-minute relearn procedure does not work, the problem may be with the reader coil. This requires testing the circuit with a multimeter and a scan tool to check for communication with the TDM.
   Typical fix: Replacement of the ignition lock cylinder assembly, which includes the reader coil. This is a more involved repair.
   Est. part cost: $100-$250 for the part (e.g., ACDelco D1403G).

Rare But Worth Checking

• Failing Body Control Module (BCM) or Theft Deterrent Module (TDM): This is rare, but if all keys and the ignition cylinder are confirmed to be working correctly, the module itself may be at fault. This is an expensive last resort and requires dealer-level programming.
• Aftermarket Electrical Interference: TSB PIC5650M also warns that aftermarket electrical accessories, particularly cheap LED headlights or USB chargers, can create enough RFI to disrupt the Passkey system and trigger security codes. One owner on YouTube traced a U0073 code, often related to security module communication, to faulty aftermarket LED headlights.

Diagnosis Steps

1. Verify the code with a scan tool capable of reading Body (B) codes.
2. Question the driver: Are they using a new key? Has the key been damaged? Did the battery recently die or get replaced?
3. Inspect the keychain. Remove all other keys, fobs, and RFID cards.
4. Attempt to start the vehicle with only the Solstice key near the ignition. If it starts, the issue is RF interference.
5. If the car still doesn't start, try a second, known-good key. If the second key works, the first key is faulty.
6. If no key works or the battery was recently changed, perform the 30-Minute Relearn Procedure: 1. Turn the key to the 'ON' position (do not start). 2. Wait for the security light to turn off, which takes about 10 minutes. 3. Turn the key 'OFF' for 5-10 seconds. 4. Repeat steps 1-3 two more times for a total of 3 cycles (~30 minutes). 5. After the third cycle, turn the key off, then attempt to start the vehicle. It should now start.
7. If the relearn procedure fails, inspect the wiring and connectors between the ignition lock cylinder and the Theft Deterrent Module (TDM) or BCM.
8. If wiring is good, use a capable scan tool to monitor the TDM data to see if it is receiving any signal from the key. This can help differentiate between a bad reader coil and a bad module.

Related Codes That Often Appear With This One

• B3055 — B3055 means 'No Transponder Modulation or No Transponder'. It often appears with B3060, indicating a problem with the key being read, either because it's the wrong key (B3060) or the signal is missing entirely (B3055). [Bulletin #PIC5650M]
• B3935 — This code is also related to the transponder circuit. It can be set along with B3055 and B3060 during an immobilizer fault event. [Bulletin #PIC5650M]

Technical Service Bulletins (TSBs) & Recalls

• PIC5650M: Addresses intermittent no-crank/no-start with security light on, citing DTCs B3055, B3060, and B3935. Points to RF interference from a wide variety of sources, including other key fobs, toll passes, and even aftermarket LED lighting, as a primary cause.

Platform-Specific Known Issues

• As documented in GM TSB PIC5650M, this platform is susceptible to intermittent no-start conditions caused by radio frequency interference from other devices on the owner's keychain.
• The 30-minute relearn procedure is frequently required after replacing the vehicle's battery, as the voltage drop can cause the TDM to lose its key memory.
• Many owner experiences on forums confirm that the first diagnostic step should always be to separate the Solstice key from all other fobs and cards.

Mechanic-Grade Diagnostic Values

• Scan Tool TDM/BCM Live Data — expected: The 'TDM Valid Key' parameter should read 'Yes' when a programmed key is in the ignition and turned to ON.. Failure: Parameter reads 'No' or does not change when a known-good key is used, indicating a problem with the reader coil or TDM/BCM.

Scan Tool Commands That Help

• GM Tech2 / equivalent professional scan tool: View TDM/BCM Data > Security Data > Valid Key — Use this to confirm if the Theft Deterrent Module (TDM) is successfully reading and validating the key's transponder. This helps differentiate between a bad key and a bad TDM or reader coil.
• HP Tuners: Relink VATS — This function can be used to attempt to re-establish communication between the ECM and the BCM/TDM after a module swap or flash, but it may still require the 30-minute relearn procedure to complete the process.

Wiring & Ground Locations

• Body Control Module (BCM) — Integrated into the fuse/relay box located in the passenger footwell, under the glove box.. The BCM is the central hub for body electronics and acts as the gateway for the security system. A failure here, often due to water intrusion, can cause a B3060 code.
• Theft Deterrent Module (TDM) — Located on the top right of the steering column, integral with the ignition lock cylinder housing. It contains the exciter coil that reads the key.. This module is directly responsible for reading the key's transponder. A failure of the TDM or its integrated coil is a direct cause of security codes.
• Ground Points G301 / G302 — G301 is located at the left 'B' pillar (behind the driver's seat). G302 is at the right 'B' pillar (behind the passenger's seat).. The BCM and other modules rely on clean grounds. A corroded or loose ground at these locations can cause intermittent and difficult-to-diagnose electrical issues, including security system faults.
• BCM Connectors — At the BCM in the passenger footwell. Connectors are designated C1 (72-pin gray), C2 (72-pin gray), C3 (41-pin red), and C4 (68-pin light gray).. Corrosion on the pins of these connectors, especially from water damage, can interrupt communication between the TDM, BCM, and ECM, triggering security faults.

Real Owner Repair Stories

• YouTube channel 'Bent Oaks Garage' (2006 Pontiac Solstice) — No crank, no start. Security light was on solid, not flashing. Gauges would sweep when trying to start.
  ❌ Tried (didn't work) The standard 30-minute relearn procedure failed because the security light would not turn off after 10 minutes.
  ✅ What actually fixed it The Body Control Module (BCM) had suffered significant water damage, evident by a visible water line on the case. The owner replaced the BCM with a used unit and cleaned the connector pins. After replacement, the car started and ran.

When the Usual Fixes Don't Work

• While the 30-minute relearn procedure is a very common fix, it is not a universal solution. A critical diagnostic detail is the state of the security light when the key is ON. If the light is flashing, the system is in a 'learnable' state and the relearn procedure is appropriate. However, if the security light is on solid and does not turn off after 10 minutes, this indicates a hard fault in the system, such as a failed BCM, TDM, or a wiring issue. In this state, the relearn procedure will not work, and parts must be tested and replaced first.

OEM Part Supersession History

• 19149941, 26085516, 26108340, 89060589 → GM 15795322 (ACDelco D1403G) — Part consolidation and revision over time.
  Heads up: When ordering, ensure the part fits the Solstice/Sky platform, as this housing was used on other GM vehicles like the Colorado/Canyon but may have slight differences.

Model Year Variations Within This Range

• 2007-2010: While the core Passkey III+ anti-theft system and the B3060 code remained consistent throughout the Solstice's production, other vehicle electronics were added in later years. 2008 models made OnStar and a driver information center standard. 2009 models made ABS and stability control standard on the base trim. These changes do not alter the B3060 diagnosis but add complexity to the vehicle's overall network.
