Detailed Product Overview

URO 1K0905851B is an ignition lock cylinder replacement for a wide range of Volkswagen and Audi vehicles. It is engineered to replace worn OE lock cylinders that can cause sticking, poor key feel, or inconsistent starter switch engagement.

This ignition lock cylinder is listed with no key included and no mounting hardware included. It features a female connector with one connector and a male terminal, and it is finished in natural silver. This part cross-references VAICO V10-5316 and ATP 101017 for the same application.

What It Helps Fix

• Starter switch engagement issues caused by a failing OE cylinder

Installation Notes

Verify vehicle-specific fitment before installation, since this part is used across multiple Volkswagen and Audi platforms. Confirm whether your application includes the ignition switch, as noted in the fitment data for select GTI, Golf, Golf Alltrack, Golf R, Golf SportWagen, and Q3 Quattro models. Professional installation is recommended when the original cylinder is seized, keyed differently, or tied to vehicle security components.
