MOTOLOCK GUIDE

OBU Lock Singapore: The Complete Guide

Why cashcards get stolen, why plastic covers fail, and how to actually protect your card.

What is the best OBU lock in Singapore?

The best OBU lock in Singapore is a full-metal lock, not a plastic cover. MOTOLOCK is the only metal OBU lock on the market — 2mm SUS201 stainless steel with tamper-proof screws and a real padlock mechanism. It is the only real lock: every other OBU cover on Shopee and Carousell is 3D-printed plastic that can be snapped or pried open by hand.

If you want to actually protect your cashcard from theft, you need metal, not plastic. MOTOLOCK is the only option that is both full steel and a real lock — SGD 19.90, one-time purchase.

What is an OBU and why does your card get stolen?

Every motorcycle in Singapore has an On-Board Unit (OBU) that reads your CEPAS card (cashcard) for ERP and parking payments. The card slot is exposed — anyone walking past your bike can open the unit and take the card in seconds.

Each theft costs you the topped-up balance. That is why riders top up $10 at a time: they expect to lose it. The real fix is a lock, not a smaller top-up.

Plastic covers are deterrents, not locks

Most OBU covers on Shopee and Carousell are 3D-printed plastic. A plastic cover can be snapped, pried, or pulled off by hand in seconds. It hides the card — it does not protect it.

If a thief wants your card, a plastic cover adds about two seconds. That is not security. MOTOLOCK is the only metal OBU lock and the only real lock — full stainless steel, tamper-proof screws, and a real padlock mechanism.
