Extremely low demand. To bring new parts to market we need a demand that covers costs.
Far fewer tailgate hatch Suburban's than Barn door Suburban & Panel trucks. We just spent a Significant sum to get barn door locks made of which barn door Suburban & Panel trucks = about 72% + of all Suburban's ( over 80,000 )made to make a complete Suburban & Panel truck Ignition, Door & Barn door lock set. Where as the tailgate hatch barely over 20,000 made.
We received 100 sets of the barn door locks. 90 were keyed 69-72 OEM GM square head key, 10 were keyed with 67-68 OEM GM octagon key head.
We listed these on our site in Dec. 2015
To date we've sold 1 set.
How long at 1 set every 3 months or so will it take to re-coup the invest on 100 sets. QUITE a while.
So if the barn door lock sets which represent 80% + of Suburban's made sell this slowly you can then imagine how quickly the tailgate version would sell.
Have you considered having a locksmith look at your current lock to get it functioning?? They can re-key or repair lock cylinders in most instances.
Sorry the news wasn't better just speaking the realities from our point of view.
