✓ Strengths

• Original Piaggio – official code 838695, not a reproduction
• Complete assembly – steering lock, key lock, and electrical connector in one piece (identified from product photos)
• New, never mounted – not reconditioned, not removed from a vehicle
• Shear-off security screws included – the shearable screws that prevent external disassembly are already on the part (identified from product photos)
• Gets the vehicle back on the road – with a faulty steering lock, the M500 won't start and can't be steered: it's a complete vehicle immobilizer

When this part is needed

When the key won't turn or turns loosely, when the engine doesn't receive power when turning to MAR, or when the steering remains locked even with the key inserted. These are the three classic symptoms of a worn-out steering lock assembly: the internal lock wears out or the electrical contacts oxidize, and the vehicle stops wherever it is. On a microcar, the stoppage is complete, as there is no way to bypass the lock without damaging the steering column.

Frequently asked questions

Is it just the mechanical lock or also the ignition?
Both. The part includes the steering lock, the key lock with STOP-PARK-MAR-AVV positions, and the electrical connector: it's the complete steering column assembly.

Are keys included?
The assembly has its own lock, so it works with its own keys and not with the vehicle's old keys: from then on, you will have one key for the ignition and, if the rest remains original, another for the doors and fuel cap. Before ordering, write to us and we will verify the exact contents of the package together.

Can I install it myself?
Better not. The fastening uses shear-off screws, which break off once tightened and cannot be removed with a screwdriver: you need to access it with the steering column disassembled and the electrical connection already verified. This is workshop work.

Is there a non-original equivalent?
No. The M500 is a limited series microcar, and this assembly has no aftermarket reproductions: there's the new original, or used parts removed from vehicles.

Will it fit my gasoline M500?
The official catalog lists this code for M500 500cc Diesel 2003-2007 and 2007-2010. For other versions, write to us with your VIN number: we'll check it.
