Whether it’s dealing with older chip systems or manual programming, we’ve got the expertise to manage even the most complex Proton key issues.

Proton Key Systems: A Technical Overview

Proton vehicles often use key systems derived from Mitsubishi, incorporating similar transponder chips and manual programming techniques. As such, many Proton models require specialized knowledge and tools to decode locks, ground diagnostic ports, and program keys correctly. Understanding these intricacies is key to providing reliable locksmith services for Proton owners.

Technical Approaches for Programming Proton Keys and Handling Lock Systems

1. Proton Gen-2: Programming Genuine and Aftermarket Keys
   The Proton Gen-2, a popular model from 2004 to 2012, typically uses a Mitsubishi-style transponder key (MIT8) with an ID48 chip. Programming a new key for this model involves connecting to the car’s onboard diagnostic (OBD) port and using manual programming techniques or a programming tool like the T300.

   In a 2010 Proton Gen-2 job, Seb successfully programmed a genuine key using the Zedfull tool. The process required grounding specific pins on the OBD port to establish a connection and inputting the required five-digit PIN code.

   • Tools Used: Zedfull, T300
   • Key Details: MIT-12.P2 Mitsubishi non-remote key
   • Challenges: Manual programming often necessitates grounding specific OBD pins, which may require additional cables such as the ADC2010 adaptive cable.

2. Working with the Proton Jumbuck – Techniques and Key Details
   The Proton Jumbuck presents unique challenges, particularly with older models that may not have standard OBD port connections. For a 2003 Jumbuck, Henry Kroll needed to manually ground the 4th and 5th pins on the OBD port using the Smart Pro tool. This procedure facilitated key programming for an aftermarket key featuring a Mitsubishi non-remote multi-function chip (MIT11R).

   • Programming Tools: Smart Pro
   • Manual Techniques: Grounding OBD pins to enable key programming
   • Key Type: MIT11R Mitsubishi non-remote key

3. Proton Persona – Common Procedures for Spare and Lost Keys
   For more recent Proton models like the 2012 Persona, manual programming methods are still often required, albeit with newer tools like the Smart Pro and VVDI Key Tool Max. In one case, Seb Winkle programmed an aftermarket spare key with a standard 48-chip using the MIT11R key blade. This required accessing the vehicle’s OBD port and following manual programming instructions to sync the key with the immobilizer.

   • Key Specifications: 48 chip with MIT11R blade
   • Tools Used: Smart Pro, VVDI Key Tool Max
   • Technical Notes: Programming may involve inputting a five-digit PIN for some models, while others use direct manual methods.

4. Decoding Locks and Key Cutting – A Focus on Proton S16
   The Proton S16, known for its practicality, also has some challenging lock systems. For example, during a 2010 Proton S16 job, the drivers’ door lock could not be removed for decoding even after the retaining bolt was removed, requiring the boot lock to be picked and decoded instead. The Smart Pro tool was then used to program a non-remote key with an ID48 chip.

   • Lock Decoding: Lishi picks may not always fit certain locks; alternative entry points such as the boot may be necessary.
   • Programming Tools: Smart Pro, VVDI Key Tool Max
   • Key Types: MFKMIT8, MIT-12.P2 for non-remote applications

5. Older Proton Models – The Basics of Manual Key Programming
   For older Proton models, such as the early 2000s vehicles, manual programming techniques are more prevalent. This includes inputting five-digit PIN codes and using standard 4C or 48-chip transponders. The T300 programming tool can be employed for older cars, such as the 2006 models with a MIT8 key blade, to manually program the key.

   • Transponder Types: 4C or 48 chip, depending on the model year
   • Programming Techniques: Manual, with a five-digit PIN requirement
   • Tool Requirements: T300, ground cables for OBD connectivity if necessary

Key Tools and Methods for Programming Proton Keys

• Zedfull: Effective for decoding Proton Gen-2 and older models, especially when manual PIN input is needed.
• Smart Pro: Versatile tool used for programming various Proton keys, including the Jumbuck and S16 models. It also allows for grounding OBD pins when required.
• VVDI Key Tool Max: Handy for programming aftermarket keys with standard chip setups like the ID48 and MIT11R.
• T300: Reliable for older Proton models using 4C chips and basic key programming functions.
• Lishi Pick: Essential for decoding boot or door locks when standard pick-and-decode approaches are not viable.

Common Issues and Challenges When Working with Proton Vehicles

1. Manual Programming Requirements
   Many Proton models still require manual programming techniques, such as grounding specific OBD pins and inputting five-digit PIN codes. This may necessitate specialized cables or adapters to establish a connection.

2. Compatibility Issues with Lishi Picks
   Not all Proton locks are compatible with Lishi picks, particularly on models like the Proton S16 where certain locks may not be accessible or removable. In these cases, decoding alternate locks, such as the boot lock, may be required.

3. Variability in Key Types and Chips
   Proton vehicles may use a variety of key types, including 4C, 48, and multi-function chips (MIT8, MIT11R). Technicians must be familiar with these variations to ensure the correct key and programming method are used.

4. Grounding OBD Ports
   Older Proton models, such as the Jumbuck, may require manual grounding of the OBD port’s 4th and 5th pins to connect the programming tool. This can add complexity to the programming process, necessitating additional adaptive cables.

5. PIN Code Retrieval and Input
   For some Proton models, particularly older ones, a five-digit PIN code is needed to complete the programming. While newer tools can often pull these codes from the vehicle, manual entry may still be necessary in certain scenarios.
