Perimeter Antenna
The signal generated by the CentralTransmitter
is carried around the designated store perimeter
by a small, embedded cable known as the
“Perimeter Antenna”. This antenna is embedded in a 1/4” wide by 1” deep saw cut around
the parking lot which is sealed using a weatherproof sealant. The location of the perimeter
antenna determines the boundary where carts will lock. The perimeter boundary is typically
identified by a thick, painted yellow line found at all parking lot exits.
The Gatekeeper Wheel
Each shopping cart is equipped with Gatekeeper’s locking wheel. Inside each
wheel is a signal receiver and locking mechanism. The receiver is factory
programmed to listen for the locking or unlocking signals emitted from the
perimeter antennas. The Gatekeeper wheel also accepts a locking or unlocking
signal from a CartKey remote control.
Anti-Tilt Bar
Each shopping cart is also equipped with an Anti-Tilt Bar. This is typically
installed on the rear wheel on the opposite side of the locking wheel. The
Anti-Tilt Bar limits the cart from being tilted back. If the cart is tipped back,
the Anti-Tilt Bar will drag on the ground, making the cart extremely difficult
to push.
CartKey
The CartKey is a handheld device used by store employees to lock or
unlock Gatekeeper wheels. The touch pad on the front of the CartKey has two
buttons labeled “Lock” and “Unlock”. Use the “Unlock” button to unlock
carts that have locked wheels. The “Lock” button can be used for different
purposes, such as locking carts stored overnight in outdoor cart corrals, as
well as to test wheels for operation. If the battery in the CartKey runs low,
the low-battery indicator light (found in the upper left-hand corner on the
front panel of the CartKey) will remain lit. Care should always be taken not
to drop or otherwise damage the CartKeys. Gatekeeper recommends that
you keep at least one CartKey in a secure location at all times in order to
avoid losing or temporarily misplacing all CartKeys.
