B3060 on 2023-2025 GMC Acadia: Unprogrammed Key and No-Start Fixes

What's Unique About the 2023-2025 Gmc ACADIA

The 2023-2025 GMC Acadia spans two different generations (the second ending in 2023 and the third beginning in 2024), both of which use a sophisticated keyless push-to-start system. These modern systems are sensitive, and issues can arise from simple things like a weak key fob battery or radio frequency interference. A GM Technical Service Bulletin (TSB PIC5650 series) for the 2023 model year acknowledges intermittent no-crank conditions related to this code, specifically advising technicians to check for aftermarket electronic devices causing RFI before replacing components. The 2024+ models utilize GM's new Vehicle Intelligence Platform (VIP) architecture, which has different programming requirements and requires specific tools like the MDI 2 for diagnostics and key learning.

Diagnostic Flowchart

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

Generation note: This range covers the end of the second generation (2017-2023) and the beginning of the third generation (2024-present). While the underlying anti-theft technology is similar, specific modules and programming procedures may differ. The provided TSB specifically mentions the 2023 model year. However, the core issue of key recognition failure applies to both generations. The location for starting the vehicle with a dead key fob also changes between generations. The 2024+ models use the newer GM Vehicle Intelligence Platform (VIP), which requires different diagnostic tools (MDI 2) and programming procedures (Techline Connect SPS2) compared to the previous Global A architecture.

Symptoms You May Notice

• Engine will not crank or turn over
• Engine starts and immediately stalls
• Security indicator light is illuminated or flashing on the dashboard.
• "Service Theft Deterrent System" message on the driver information center.
• "No Remote Detected" or "Place Transmitter in Pocket to Start" message on the DIC.

Most Likely Causes

1. Unprogrammed or New Key Fob 🔴 High Probability → Shop Keyless Entry Transmitter Any new or replacement key fob must be electronically paired with the vehicle's immobilizer system before it will be recognized.
   How to confirm: Attempt to start the vehicle with a different, known-good key. If the other key works, the new key is the issue.
   Typical fix: The key fob must be programmed to the vehicle using a compatible professional scan tool and GM-specific software.
   Est. part cost: $0 (if reprogramming existing key) - $400 (for new key and programming)
2. Weak or Dead Key Fob Battery 🟡 Medium Probability → Shop Vehicle Battery The key fob's transponder requires sufficient battery power to communicate with the car. A weak signal can be misinterpreted as an invalid key.
   How to confirm: Replace the CR2032 battery in the key fob. If the battery is dead, the vehicle can still be started by placing the fob in a specific transmitter pocket.
   Typical fix: Replace the CR2032 battery in the key fob.
   Est. part cost: $5-$15
3. Radio Frequency (RF) Interference 🟡 Medium Probability Strong RF signals from devices like aftermarket LED lights, cell phone chargers, or even building access cards can 'jam' the 125 kHz, 315 MHz, or 433 MHz signals used by the key and immobilizer system.
   How to confirm: Remove other electronic devices, key fobs, or access cards from the keychain and the vehicle's interior. Unplug any aftermarket chargers or accessories. Try starting the vehicle again. TSB PIC5650M specifically instructs technicians to investigate this before replacing parts.
   Typical fix: Isolate the key fob from other electronic devices and remove any aftermarket accessories causing interference.
   Est. part cost: $0
4. Theft Deterrent Module (TDM) or Body Control Module (BCM) Fault ⚪ Low Probability → Shop Anti-Theft Control Module Electrical issues or software glitches can cause the module to lose its programming or fail to communicate properly. The TSB for the 2023 model suggests this is a known potential failure point, often triggered by underlying issues like RFI.
   How to confirm: A professional scan tool is needed to check for communication with the TDM/BCM and to see if it retains key programming information. Diagnosis costs typically range from $49 to $72.
   Typical fix: The module may need to be reprogrammed or, in rare cases, replaced and then programmed by a dealership or certified shop.
   Est. part cost: $300-$800

Rare But Worth Checking

• Faulty Immobilizer Antenna/Exciter Ring: → Shop Antenna The antenna ring around the ignition (or in the keyless receiver) energizes the transponder. If it fails, the key's code can't be read, even if the key is good. This is less common than key or module issues.
• Wiring or Connector Issue: An intermittent no-start condition, as mentioned in the TSB, can sometimes be traced to a loose connection or damaged wire at the BCM or immobilizer module, particularly after other service work has been performed.

Diagnosis Steps

1. Verify the symptom: Confirm the no-crank/no-start condition and check for a security light or message on the dash.
2. Try the spare key: If you have a second key, try to start the vehicle with it. If it works, the problem is with the first key.
3. Replace the key fob battery: This is a simple and inexpensive first step, using a CR2032 battery.
4. Check for RF interference: Per TSB PIC5650M, remove all non-essential electronics from the vehicle, especially aftermarket phone chargers and LED lights, and try again.
5. Use the dead-fob starting procedure: Place the key fob in the designated transmitter pocket and try to start the engine. For 2017-2023 models, this is a slot inside the center console storage bin. For 2024+ models, it is typically located in the driver's side cup holder.
6. Scan for codes: Use an OBD-II scanner to confirm B3060 and look for other related codes like B3055 or B3935.
7. Attempt Key Relearn Procedure: While some older GM vehicles have a manual 30-minute relearn procedure (cycling the key for 10 minutes three times), this generally does not apply to modern push-to-start models like the 2023-2025 Acadia. Professional tools are required.
8. Professional Diagnosis: If the above steps fail, the vehicle must be taken to a dealer or qualified auto locksmith to diagnose the TDM/BCM and perform key reprogramming.

Related Codes That Often Appear With This One

• B3055 — This code means 'Key Not Detected' and often appears with B3060. It indicates the system is having trouble reading the key transponder signal, which could be due to a weak fob battery, interference, or a faulty key.
• B3935 — This is another transponder-related code that can be set alongside B3060 and B3055, pointing to a general failure within the immobilizer system.

Technical Service Bulletins (TSBs) & Recalls

• PIC5650M: Addresses an intermittent no crank, no start, or start stall concern with the security light on and DTCs B3055, B3060, or B3935 set. It strongly emphasizes checking for RFI from aftermarket devices.
• 01-00-89-010S: A general guide for dealers on how to handle intermittent customer concerns, which references PIC5650 as a key document for diagnosing RFI-related issues.

Platform-Specific Known Issues

• A Technical Service Bulletin (PIC5650M) was issued for the 2023 model year regarding intermittent no-crank/no-start conditions with security codes B3055, B3060, and B3935. The primary diagnostic step is to identify and remove sources of Radio Frequency Interference (RFI) from aftermarket accessories before replacing any modules.
• The location of the transmitter pocket for starting the vehicle with a dead key fob changed between the 2nd generation (2017-2023) and 3rd generation (2024+). For 2017-2023 models, it's a slot inside the center console bin. For 2024+ models, it's in the driver's side cup holder.

Hidden / Shadow Codes Worth Checking

• B3060 00: Unprogrammed Transponder Identification Code Received. This is the most common variant, indicating a key was read but is not learned by the BCM/TDM. (see via A professional scan tool like GM GDS2 is required to view symptom bytes.)

Scan Tool Commands That Help

• GM GDS2 (Global Diagnostic System 2): Module Diagnostics > Body Control Module > Data Display > Immobilizer Data — To view live data from the immobilizer system, such as the number of learned keys, the state of the key being read, and if a valid password has been sent to the ECM. This helps confirm if the BCM is seeing the key correctly.
• GM Techline Connect (SPS2): Service Programming System (SPS) > Program Transponder or Remote Key (Add/Replace) — This is the required function for programming new or existing keys to the vehicle. It involves a security wait time (often 10-12 minutes) and must be done with a J2534 interface tool and an active subscription.
• GM GDS2 (Global Diagnostic System 2): Clear All DTCs — After a successful key relearn or repair, this command is used to clear the history B3060 code. A current B3060 will clear on its own once a valid, learned key is detected.

Wiring & Ground Locations

• G303 — Near the base of the left 'B' pillar (the pillar between the front and rear doors).. This is a major ground point for multiple interior components, including potentially the Body Control Module (BCM) or related circuits. A poor or corroded ground at G303 can cause intermittent and difficult-to-diagnose electrical issues, including communication problems within the anti-theft system.
• K9 Body Control Module (BCM) — For 2017-2023 models, it is typically located in the center console area, accessible from the passenger side footwell. For 2024+ models, it is often under the driver's side of the dashboard.. This is the central module that manages the anti-theft system and key programming. All diagnostic and repair efforts for B3060 will center on communicating with and potentially reprogramming or replacing this module.
• Data Link Connector (DLC) — Under the driver's side dashboard, to the left of the steering column.. This is the port where a scan tool or J2534 programming device connects to the vehicle's communication network to diagnose codes, view data, and perform key programming procedures.

Model Year Variations Within This Range

• 2024-2025: These models use GM's new Vehicle Intelligence Platform (VIP) electrical architecture. This system requires the MDI 2 diagnostic interface and Techline Connect (SPS2) software for all key programming and module setup. Older MDI 1 tools are not compatible. Programming procedures may also differ, such as requiring the ignition to be OFF for certain steps to prevent errors.
• 2023: This model year uses the previous generation Global A electrical architecture. While still requiring a professional scan tool and software for key programming, it is compatible with a wider range of diagnostic tools, including the MDI 1.
