Vapormatic’s new vehicle keypad immobiliser has gained Thatcham approval, meaning vehicles fitted with it can get a significant reduction in insurance premiums.

With tractor theft on the increase, Vapormatic believes personal identification numbers, or PIN codes, could provide the answer for those looking to make their machines more secure.

The version launched at LAMMA uses DD2+ technology with a wireless keypad installed in the cab. Each keypad can accept up to five different pin numbers and there is a master code for whoever is in charge.

Typically, the system cuts into the tractors fuel management system and there are two blockers giving double the protection. The unit costs in the region of £250 and fitting, which takes about two hours, needs to be done by an accredited engineer.
