I am trying to find out if my truck listed above ext cab, SLS model has a keyless entry. It’s a basic trim package. Thank you.

It was an option for this model year but that does not mean all trucks where built with it.

The easiest way to find out if you have it is one of two ways. First, contact a dealer and ask them to run your VIN and see if the sale codes are on there. If so, you should be able to just get the remotes and program them.

The other way, is to inspect the truck for a RCDLR which is the receiver that accepts the signal from the remote. If there is a receiver then it is equipped with this system. I attached the location below on this which is under the dash close to the DLC which is where you connect a scan tool to check for codes.

Please let us know if you have other questions. Thanks
