SilverBox Style Theftlock Reset

GM Navigation Radio Theftlock reset service for the ‘Silver Box’ units. These are the GM navigation radios, which have an internal hard drive and remote display screen and controls. If you are reading this, you likely have “Theftlock”, “Theftlocked”, or “LOCKED” displayed on your factory GM navigation system display. Or, perhaps you are considering installation of a surplus or salvage factory navigation console in your vehicle (from ebay, junk yard, etc), and know that it will not work unless it is unlocked. Simply send us your navigation unit (no screen) and we will send it back unlocked and ready to work in your vehicle. Great approach to upgrade a stock radio to a factory GPS navigation unit.

  • Upgrade your vehicle to a premium factory navigation system
  • No need to spend $1,200 – $2,000 for a new navigation radio, use a much lower cost surplus or salvage unit from a similar vehicle
  • Unlock any compatible factory navigation system for use in your vehicle
  • Great service for do-it-yourselfers, avoid the dealer hassle



Very few GM dealers will provide this unlock service. For the knowledgeable and helpful dealers who do provide the radio VIN relearn service, they will hit you up for an hour’s labor charge – typically $85 or more. Avoid the dealer hassle.

In addition to unlocking, we will also fully test your radio or navigation unit – checking for any past fault codes that would indicate any intermittent problems.
The navigation radio will be fully tested for…

  • Touch screen operation and display (and motor control for CTS/SRX)
  • AM/FM/XM/GPS antenna inputs
  • Navigation map
  • Center console communication (button recognition & backlighting control)
  • All speaker outputs
  • Fault codes checked (DTCs)
  • CD/MP3 function
  • Hard drive function
  • DVD playback (on-screen and remote output – if equipped)
  • Backup camera input (if equipped)

NOTE: We don’t perform radio repairs, but we will note any issues – should you wish to address them with the original provider of the unit.

Unlock service provided for all newer model Silverbox radios made for GM by Denso, Bosch, etc.. To confirm, please check the photos below and supported vehicle list.
