Compatible  with  2021 and newer Mercedes S-Class,  all variations including  Hybrid

This is not a stand-alone device. Must be connected to and controlled by a GPS tracker,  immobilizer,  breathalyzer,  car security system or similar, with a negative output trigger. It will prevent the vehicle from starting once triggered. Applications include: fleet management, rental car, anti-theft, etc.

It disables the vehicle from starting, it is tamper-proof and delivering high security. Reduces the installation complexity and increases significantly the reliability.

Detailed installation instructions with pictures. 

Pre-made harness for easy installation available upon request for selected GPS tracking devices.

Compatible with negative trigger output control devices. 

Digital input, designed specifically to read CAN bus communication of Mercedes cars. 

Status indication (optional). 

Zero surges, back EMF or spikes while operating. No need for transient suppression, clamping, etc. to drive the device, unlike driving a relay. 

Small footprint - only 1/4 the size of a commonly used relays.

Extremely durable. 

Extremely small power consumption (5% of that on a conventional relay), waterproof, can withstand extreme temperatures and pressure, ESD protection on all inputs and outputs, high input impedance, reverse polarity protection, built with premium automotive grade components from US, Japanese and German companies only (NXP, TE Connectivity, Infenion, ON-Semicon, Panasonic,  Kemet, Rohm, Vishay).

Made in New York, USA

Lifetime warranty

WHY STARTBLOCKER

Just 5 years ago, installing a device to immobilize any vehicle was down to interrupting a single analog starter wire with the external or built-in relay of any car alarm, GPS tracker or a Breathalyzer. Today, over 50% of the new cars sold on the market come with Push-to-start (PTS) button instead of a key with blade which you need to insert and turn to start. Majority of the newer vehicles are equipped with immobilizer systems to prevent theft. The PTS vehicles use radio frequencies to authenticate the car key, alternatively a RFID transponder if the key battery is depleted and emergency start is required. All those systems responsible for the key authentification are usually spread around the vehicle in a hard to reach locations and use high speed data signals over CAN network instead of analog signals to communicate. Interrupting any of those data lines to prevent a car from starting is a terrible idea, very likely to cause a very expensive visit to the dealer due to failure of electronic modules, or even a car accident. Alternatively,  installers often interrupt the brake signal to prevent starting, which not only disables the brake light, causing a safety hazard and potentially accident, also is illegal. Furthermore,  the brake signal is used in many cars to trigger the ESP and/or ABS system,  causing even greater danger for the passengers, nearby drivers and pedestrians. In other cases, installers of forementioned devices are often forced to run wires to the engine compartment through the firewall, in order to interrupt the starter. That's usually accomplished by drilling holes in the metal firewall or rubber grommets and bushings, causing leaks, potential short between wires and ultimately voiding the warranty, also very expensive repairs. In addition, it's very time consuming.

Today we have STARTBLOCKER and it's now easy to accomplish it fast and safely.
