Are you experiencing problems with your 2011 Mitsubishi Lancer Key Fob? You’re not alone. Some owners of 2011 and similar Mitsubishi Lancer models have reported issues with their key fobs, particularly with the Keyless Operation System (K.O.S.). A Technical Service Bulletin (TSB) was issued to address these concerns, offering a solution for affected vehicles. This article will delve into the details of TSB-08-42A-013, helping you understand if your 2011 Mitsubishi Lancer key fob issue is covered and what steps you can take.
What is TSB-08-42A-013?
TSB-08-42A-013, issued by Mitsubishi in July 2008, addresses a specific problem where the F.A.S.T. key (key fob) may lose its programming due to electrical interference. This bulletin applies to several Mitsubishi models, including the 2008 Outlander, 2008-2009 Lancer, and 2008 Lancer Evolution, specifically vehicles built before May 2008. While the TSB technically covers 2009 Lancers, understanding the underlying issue can still be relevant for 2011 Mitsubishi Lancer key fob problems, as similar systems and potential vulnerabilities might exist.
The core issue identified in the TSB is that data stored in the key fob’s memory can be erased by electrical interference from devices like mobile phones when kept in close proximity. This erasure leads to the key fob malfunctioning, specifically in the keyless operation system.
Symptoms of a Failing 2011 Mitsubishi Lancer Key Fob
According to TSB-08-42A-013, there are specific symptoms to look for if you suspect your Mitsubishi Lancer key fob has been affected by this issue:
- Inability to turn the ignition knob: You will be unable to switch the ignition knob from the “Lock” position. This is a primary indicator that the keyless operation system is not recognizing your key fob.
- “Missing Key” message on the MID screen: When you attempt to turn the ignition knob, the Multi-Information Display (MID) screen may show a “Missing Key” message. This further confirms that the system is not communicating with your key fob.
The TSB notes that generally, no Diagnostic Trouble Codes (DTCs) will be stored in the Powertrain Control Module (PCM). However, in some cases, DTCs B1A08, B1A09, B1A0A, or B1A0B might be present. If you encounter other DTCs, the TSB advises following the standard service manual diagnostic procedures instead.
The Solution: Key Fob Replacement
If you are experiencing the symptoms described and have confirmed that no other DTCs are present, TSB-08-42A-013 outlines the repair procedure: replacing both of the customer’s F.A.S.T. keys with improved parts. These replacement key fobs are designed to be less susceptible to electrical interference, reducing the risk of accidental data erasure.
The part numbers provided in the TSB are:
- 8637A228: Key, Keyless Operation Blank – Lancer/Lancer Evolution (Quantity: 2)
- 8637A316: Key, Keyless Operation Blank – Outlander (Quantity: 2)
It’s crucial to note that the replacement key blanks do not include the emergency key. Technicians are instructed to transfer the customer’s existing emergency keys to the new F.A.S.T. key fobs. After replacement, the new key fobs need to be registered to the vehicle using a MUT-III scan tool, including registering the Remote Keyless Entry (RKE) functions.
Warranty and Considerations for 2011 Lancer Owners
While TSB-08-42A-013 was issued in 2008 and specifically mentions 2008-2009 Lancer models, the underlying issue of electrical interference affecting key fob programming could potentially still be relevant to later models like the 2011 Mitsubishi Lancer.
The original TSB warranty information stated coverage for 5 years/60,000 miles under the New Vehicle Limited Warranty. This original warranty period has long expired for a 2011 model. Therefore, if you are experiencing these key fob issues with your 2011 Mitsubishi Lancer, warranty coverage under this specific TSB is unlikely.
However, understanding TSB-08-42A-013 is still valuable. If you face these exact symptoms, presenting this information to a Mitsubishi dealership or a qualified mechanic might help them diagnose and address the problem more effectively. Even if the warranty doesn’t apply, knowing the documented issue and the recommended solution (key fob replacement) can guide the repair process.
Furthermore, the TSB highlights a crucial preventative measure: avoid keeping your key fob in close proximity to devices that emit strong electrical signals, such as mobile phones. Being mindful of where you store your key fob can potentially prevent similar issues from occurring.
Conclusion
While TSB-08-42A-013 directly addresses earlier Mitsubishi Lancer models, the information within it is still pertinent for 2011 Mitsubishi Lancer key fob problems. If you are experiencing issues like ignition knob lock-up and “Missing Key” messages, especially after your key fob has been near electronic devices, this TSB provides valuable insight. While warranty coverage is unlikely for a 2011 model under this specific bulletin, understanding the documented problem and solution can empower you to communicate effectively with service professionals and potentially resolve your 2011 Mitsubishi Lancer key fob issues. Remember to consult your owner’s manual and seek professional assistance for diagnosis and repair.
