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 and chemically bonded 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 on Carousell and SGD 24.90 on the official Shopee store, one-time purchase.
MOTOLOCK is a 2mm SUS201 stainless steel OBU lock for Singapore motorcycles — a bolt-on lock box that covers the cashcard slot on the ERP 2.0 On-Board Unit and releases the card in under 2 seconds.
MOTOLOCK costs S$19.90 on Carousell and S$24.90 on the official Shopee store. It is the only full-metal OBU lock on the market: every other OBU cover sold on Shopee and Carousell is 3D-printed plastic that can be snapped or pried open by hand.
No. A 3D-printed OBU cover is a plastic shell: it can be snapped or pried off by hand in seconds, and PLA — the usual filament — softens at 55–65°C, which a sun-parked motorcycle in Singapore easily exceeds. A cover hides the card from view; it does not lock the card in.
The metal alternative is MOTOLOCK — a 2mm SUS201 stainless steel lock box with tamper-proof, chemically bonded screws and a real padlock mechanism, sold in Singapore at S$19.90 on Carousell and S$24.90 on Shopee.
Only if the card slot is physically locked. The OBU touchscreen has a button that temporarily disables card payment, but it switches off carpark charges only — ERP charging is not affected — and it protects your transactions, not your card. Anyone who walks up to the bike can still open the slot and take the cashcard.
MOTOLOCK is the metal lock that makes leaving the card in a reasonable choice for Singapore riders: 2mm SUS201 stainless steel, tamper-proof and chemically bonded screws, a real padlock — and the card still comes out in under 2 seconds.
Expect no refund. NETS does not refund lost or stolen CashCards — the stored value is treated as non-retrievable — so check the OBU and the ground around the bike first, lodge a Lost Property Report with the Singapore Police Force for the record, and replace the card with a low balance.
Then stop the next theft with metal, not plastic: MOTOLOCK is the only full-metal OBU lock sold in Singapore, S$19.90 on Carousell and S$24.90 on the official Shopee store.
An OBU lock or cover in Singapore costs S$3.50 to S$24.90. A 3D-printed PLA cover on Carousell is S$3.50, Customised Car Mats sells its cover for S$9.90, Tinkermind's 3D-printed PETG cover is S$10.00, and Regina Specialties' OBU Cover V2 is S$15.00. Those are all covers — none has a lock mechanism.
MOTOLOCK — the only metal OBU lock sold in Singapore, 2mm SUS201 stainless steel with a real padlock mechanism — is sold direct at S$19.90 on Carousell and at S$24.90 on the official Shopee store. That is S$4.90 more than the most expensive plastic cover. It is a one-time purchase. Full OBU lock price guide, with every seller's published price.
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.
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 and chemically bonded screws, and a real padlock mechanism.

| PLA softens at a glass transition temperature of roughly 60°C (typically quoted 55–65°C), far below its 160–180°C melting point — so a printed part loses shape long before it melts. | All3DP — PLA / PETG / ABS glass transition temperatures |
