2002 Blazer LS keyless entry

I just bought a 02 Blazer LS. The dealer did not have a key fob. How can I tell if this vehicle is set up for keyless entry? Thanks.

Call the dealer with your vin#.

or drop the plastic cover under the dash on the drivers side. There will be a box in the left corner near the e brake attached to the plastic cover.

Look on the RPO sticker on the inside of the glove box door. The RPO code for keyless entry is AU0. If you have that code, call the dealer with your VIN number and get the part number of the transmitter you need.
