Anti-start utility on your Chevrolet Suburban:

This tool is as expected used as an anti-theft protection. Indeed, it is programmed in order to start your Chevrolet Suburban exclusively if the key which includes this code is inserted. We think of these movies where thieves operate a few wires under the dashboard to start the engine, which is impossible with the anti-start system.

Anti-start operation on your Chevrolet Suburban:

To put it simply, we have a transmitter and a receiver that work together to validate the operation and consequently switch on the engine. The immobilizer provides the transmitter, and will consequently issue a code request when the key is inserted in your Chevrolet Suburban. Think of this transmitter as a doorkeeper who would ask for an a way in code when someone knocked at the door.
This code request is provided to the key, which subsequently, sends a unique user code, specific to the start system, and in the event this code matches, then the anti-start will allow the engine start.
The procedure is very simple. However, when mentionning double safety, we also suggest potentially more possibilities of breakdowns or various failures unfortunately.
In the next paragraph, you will find the various breakdowns you could experience on your Chevrolet Suburban.

Immobilizer failures:

There may be various factors that prevent your Chevrolet Suburban from starting because of the immobilizer. First of all, stupidly, you’re not using the right key. It may seem superficial but it happens!
If you have the right key, you have two options left:

  • Option n1: The transmitter is involved, so the immobilizer. Usually, it is easy to detect if you have a duplicate key. If, with the two keys of your Chevrolet Suburban, you have the same problem, then it is the anti-start that is faulty and therefore must be replaced or disabled. Completing this task will cost less than replacing it, but your car will be more subjected to to theft and your insurance may not cover you if your car is stolen.
  • Option n2: The problem comes from the receiver, the key, which transponder has been harmed. This can be changed for less money by a professional than the anti-start system.

If you speak to your mechanic, he will obviously offer to tow your Chevrolet Suburban and charge a high price for everything, he will not give you the code quite readily. For security reasons alone, it is legally impossible to transmit the code to you. You must send your car.

Conclusion

  • – First try to find where the failure on your Chevrolet Suburban came from. Then act accordingly. It would be a pity to replace the entire immobilizer system when the key is defective.
  • – Make a quote at a garage and then consider an replacement at an online professional, which will often be more efficient and less expensive.
