Hello everyone. I am the San Antonio distributor for the Ravelco Anti-theft device: Ravelco Engine-Lock - Car & Truck Anti-Theft Device - San Antonio, TX. The Ravelco is a 40 year old device that makes hard wire engine connections to immobilize start and run functions. The 16 pin security plug connects in the dash and is carried on your key chain.

Millions of cars and trucks have been protected over the decades. It contains no computer chip, no RFID signals and is not powered by a hot wire connection. This means that manipulating the unit in the cab will NOT disable the anti-theft protection in the engine compartment. It is NOT an alarm. It prevents hot-wiring and computer code manipulation theft.

Almost all of our business is word-of-mouth because customers enjoy having that 16 pin security plug in their pocket knowing their truck will be where they parked it when they return.

Our phone number is 210 547-1699. I will be happy to answer any questions you have here on the forum.
