I cannot speak for the effectiveness of alarms, but I did help a few neighbors install alarms, including one that was 2 way, the remote would indicate if the alarm was activated (1/2 mile range if I recall correctly).

How many times has anyone heard a car alarm blaring and just ignored it as it happened so often? And of course, on a golf cart they can simply pull the wire off the alarm horn.

In "the old days" (back in "the 80's :)) I used to have an alarm on my new car that would YELL (with a voice) if anyone got too close and heaven forbid they actually touched it. :1rotfl: Alarms are so 20th century. :D

Wonder if this is just one group doing the theft?

Seen them too. Cartful of kids with swimming suits. On the way to the free pools

So, did you call anybody? Did you see them go to a pool? Did you alert the rec center?

Random Key
 

Put a “random key” ignition on your Yamahas, the key provided with most carts is a generic type manufactured ignition key that fits all the Yamaha golf carts. A random ignition is super easy to install (Less than 5 minutes). They are about $50.

And likely just as easy to remove/bypass (or just roll up onto a truck). I pushed some guys GC into the middle of a parking lot a couple of years ago without needing a key when he parked directly behind me at a Walmart. Simply released the brake and rolled it practically to the front door of Walmart who refused to try and page them (which wouldn't have helped anyway).
