RAM® Pin-Lock™ 替換用 4 針鑰匙（適用於 C 尺寸及擺動臂）

The 4-pin pattern on this replacement key lined up perfectly with my existing C-size swing arm lock, so swapping the old one out took maybe two minutes. Feels solid and clicks into place just like the original, which is exactly what I needed.

I dropped my original key while hiking, and this replacement pin locks into the 4-node pattern just like the factory one did. The knob feels solid and turns smoothly without any wobble.

I was worried the key wouldn't match the pattern on my older C-size mount, but each of the four pins clicked in perfectly. The solid plastic knob feels durable enough for daily use.
