Vehicle theft is one of the most widespread criminal activities. Every year, hundreds of thousands are stolen in Europe, anda few million worldwide.

This is because for an experienced criminal, car theft is a simple affair. Vehicles are stolenmainly for spare parts, or organised gangs export them to neighbouring countries. As such, it is almost impossible to trace them.


A reliable means to prevent vehicle theft is a mechanicalgear lever lock, which locks the moving parts of the gear mechanism.

It is locked in reverse (for manual transmission) or in the parking position (for automatic transmission), and as a result it is impossible to drive off in the vehicle.

The manufacturer assumes liability for the quality of the CONSTRUCT Group products (hereunder in the text also referred to as the “product”). The warranty includes entitlement to replacement or repair of product defects due to material or processing defects, but only upon compliance with the specified conditions and exceptions stipulated hereof.
