Piaggio 838695 Steering Lock with Ignition Switch – Microcar M500 Diesel

The Piaggio code 838695 is the steering lock assembly with ignition switch for the Microcar M500 500cc Diesel. It is not just a mechanical lock: it also includes the key lock cylinder with STOP · PARK · MAR · START positions and the seven-pin electrical connector that powers the system (as identified from product photographs). It features a die-cast alloy body with a steering column collar and two break-off security screws.

✓ Strengths

• Original Piaggio – official code 838695, not a reproduction
• Complete assembly – steering lock, key lock, and electrical connector in one unit (as identified from product photographs)
• New, never fitted – not refurbished, not removed from a vehicle
• Break-off security screws included – the shear bolts that prevent removal from the outside are already on the part (as identified from product photographs)
• Gets the vehicle back on the road – with a faulty steering lock, the M500 will not start and the steering will not turn: it causes a complete vehicle breakdown

When is this part needed

When the key will not turn or spins freely, when the engine does not receive power when switched 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 cylinder wears out or the electrical contacts oxidize, and the vehicle stops exactly where it is. On a microcar, the breakdown is complete, because there is no way to bypass the lock without damaging the steering column.

Frequently Asked Questions

Is it just the mechanical lock or the ignition as well?
Both. The part includes the steering lock, the key lock cylinder with STOP-PARK-MAR-START positions, and the electrical connector: it is the complete steering column assembly.

Are keys included?
The unit has its own lock, so it works with its own keys and not your old vehicle keys: from that moment on, you will have one key for the ignition and, if the rest remains original, another one 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?
It is better not to. It is secured with break-off screws, which shear off once tightened and cannot be removed with a screwdriver: you need to access it with the steering column removed and the electrical connection already verified. This is a job for a workshop.

Is there a non-original equivalent?
No. The M500 is a limited-series microcar and this assembly has no third-party reproductions: there is only the original new part, or a salvaged used one.

Is it suitable for my petrol M500?
The official catalog lists this code for M500 500cc Diesel models from 2003-2007 and 2007-2010. For other versions, write to us with your VIN; we will verify it for you.
