美国采购需求：凸轮锁更换、橱柜密码锁、无钥匙凸轮锁、安全储物锁、可调凸轮锁、抽屉锁定机制

I'm reaching out to get detailed pricing and options for various car locks. We're interested in understanding the different types available, including any features that stand out. It would be helpful if you could also include information on bulk purchase discounts and lead times for delivery. Additionally, if you have any recommendations based on durability, security ratings, or customer reviews, please share those insights as well. We're looking to make a decision soon, so any info you can provide would be greatly appreciated. Thanks!
