2-Stage programming is the process where a customer or end-user initially installs the kit, and programs/syncs the remote start module to the vehicle via included instructions – Stage 1 complete.

Then the customer, either sends the module back to N2 Designs to apply the decryption, or decrypts it themselves with our instructions depending on what option was chosen at the time of checkout. – Stage 2 complete.

Decryption is the process of allowing the remote starter module to learn the keycodes your vehicle uses to activate and deactivate the security and anti-theft device built into all modern vehicles. Most key fobs use a Radio Frequency Identification (RFID) transponder to enable it to unlock the vehicle and perform a variety of additional functions.

1. The key fob sends encrypted data to the vehicle; this is often a rolling code that allows the vehicle to ID the key fob.

2. The vehicle then decrypts this data and uses the decrypted data to authenticate that this particular key fob should unlock this vehicle.

3. Authentication is performed by the vehicle immobilizer, an anti-theft system within the car. The car cannot be started until the immobilizer successfully authenticates a key fob to prevent hotwiring of the vehicle by thieves.

Due to the variance in anti-theft hardware utilized by various vehicle manufacturers. Some vehicles require decryption while others do not. This will depend on the year, make and model for your vehicle.

Currently there is no way to bypass the need for vehicles that require “Decryption” due to the fact that our remote start kits do not modify any software that is used in your vehicle’s computers. This allows our kits to remain plug and play and easily installed by the end user.

Currently N2 Designs, Inc. Offers two options for Decryption: 1: Remote decryption with the purchase of the N2 Decryption Tool at the time of checkout. This option will require access to a windows-based PC and stable internet.

2. The second option is to send your N2 remote start module back to N2 Designs, Inc. And allow our in-house technicians to perform the decryption process for you. You can select this option from the drop-down list at the time of check out when purchasing your N2 remote start kit. This option gives you a return label to make the process hassle free and covers the return shipping back to you.

You will be given a choice from a drop down menu on each respective listing that requires this process before place a decryption-required kit into your checkout cart.
