Experiencing intermittent issues with your 2006 Mazdaspeed 6 Key Fob can be frustrating. It’s a common problem where sometimes the advanced entry system fails to activate either the ignition or door entry. You might find yourself tapping the key fob in hopes it will work, highlighting an issue beyond simple remote battery problems. Let’s delve into diagnosing why your programmed key might not be consistently opening your doors or starting your ignition.
Let’s clarify what’s working correctly. You’ve confirmed that the fob’s unlock and lock buttons are functioning, and the physical keys operate as expected. This isolates the problem to the advanced keyless entry and ignition system of your 2006 MAZDASPEED 6. You’ve also already taken crucial steps to rule out basic causes:
- Remote Batteries: You’ve confirmed the batteries in your 2006 MAZDASPEED 6 key fob are in good condition.
- Electrical Contacts: You’ve ensured the electrical contact pads are properly touching the battery, eliminating loose connections.
- Battery Security: You even tried a paper shim to secure the negative pad, showing a thorough approach to battery issues.
- Push Buttons: Checks on driver, passenger, and trunk push buttons have been performed, including repairing corroded connectors at the front buttons.
Despite these efforts, and even after Mazda dealers and locksmiths attempted to pair or re-pair keys to your MAZDASPEED 6, the problem persists. A locksmith’s system diagnostic indicated no issues with the security system itself, yet the key fob functionality remains unreliable beyond the basic lock/unlock buttons.
The locksmith’s suspicion pointing towards car modules could be on the right track. Here are potential areas within your 2006 MAZDASPEED 6 to investigate further:
- Key Fob Internal Issues: While the buttons work, there could be internal circuitry problems within the 2006 MAZDASPEED 6 key fob affecting the advanced entry and ignition signals. Even though diagnostics passed, intermittent faults can be tricky to pinpoint.
- Car’s Receiver/Antenna: The signal from your 2006 MAZDASPEED 6 key fob is received by an antenna and receiver module in your car. A weak signal due to antenna issues or a faulty receiver could cause intermittent problems.
- Immobilizer System: The immobilizer is an anti-theft system that needs to recognize the key fob to allow ignition. If there are glitches in the immobilizer communication, it could prevent the car from starting even if the key is programmed.
- BCM (Body Control Module) or PCM (Powertrain Control Module): These modules are central to many car functions, including security and keyless entry. Problems within these modules, as suggested by the locksmith, could be the root cause.
Given the troubleshooting already done, professional diagnostics are likely necessary. A technician specializing in automotive electronics and security systems can further investigate the car’s receiver, modules, and immobilizer system to pinpoint the exact cause of your 2006 MAZDASPEED 6 key fob issues.
