Autoloc is proud to introduce our new line of TailLoc tailgate locking systems for the 1999 or 2002 Chevy Silverado or GMC Sierra. TailLoc insures the protection of both your tailgate and the contents of your Chevy Silverado or GMC Sierra by automatically locking when you lock your doors. Optional dash switch is available for Chevy Silverado or GMC Sierras without power locks or for those who want to operate their TailLoc independently. To insure maximum protection TailLoc mounts inside your Chevy Silverado or GMC Sierras tailgate, hidden from view. Simple installation and detailed instructions mean you can forever protect yourself from theft in 30 minutes, using only basic hand tools. The TL2 TailLoc system is designed specifically for your Chevy Silverado or GMC Sierra and is manufactured in the USA. Backed by a limited LIFETIME WARRANTY.
