We're a certified vendor and repair specialist for the three most widely used cart containment systems in Southern California — Gatekeeper, Rocateq, and Carttronics.
What are cart containment wheels?
Cart containment systems use specially designed electronic wheels that lock automatically when a shopping cart is pushed beyond a designated perimeter — typically the edge of a parking lot. When triggered by a buried wire or radio frequency signal, the wheel locks in place, stopping the cart and protecting your inventory. West Coast Shopping Cart Service installs, services, and repairs all three leading systems.
Gatekeeper is the industry standard for electronic cart containment, protecting millions of carts at retailers across North America. Their Intellilock wheels lock automatically when a cart approaches a buried perimeter wire at the lot's edge — no staff required. Once locked, the cart cannot be pushed further off-property, and it automatically resets when returned inside the perimeter.
Rocateq uses radio frequency technology to define a virtual perimeter around your property. Their distinctive red-capped caster locks the cart wheel the moment it crosses the RF boundary — without any buried wire infrastructure. This makes Rocateq particularly popular for retrofitting existing lots and locations where trenching isn't practical.
Carttronics' CAPS (Cart Access & Payment System) casters bring containment and access control together in one rugged unit. Common at Costco, Aldi, and select Walmart locations, CAPS casters can be paired with coin-deposit mechanisms or standalone containment perimeters. The heavy-duty chrome yoke and reinforced housing make them one of the most durable systems on the market.
Whether your system is Gatekeeper, Rocateq, or Carttronics — we carry replacement casters and can service your fleet on-site across Southern California.
