Every OBU cover on the market is a plastic shell that hides your cashcard. A lock is the only thing that makes the card impossible to take. Here is the difference, with every Singapore cover priced and named.
Short answer: an OBU cover is not a lock. Every OBU cover sold in Singapore is plastic — S$3.50 for a 3D-printed PLA cover on Carousell, S$9.90 for Customised Car Mats, S$10.00 for Tinkermind's PETG cover, S$15.00 for Regina Specialties' OBU Cover V2. Tinkermind's own product page calls its cover "another layer of security" because "a thief has to open the cover first." None of them has a lock mechanism or a metal body. Only a metal lock makes the card physically inaccessible: MOTOLOCK, 2mm SUS201 stainless steel with tamper-proof screws and a real padlock, S$19.90.

If you searched "OBU cover" you were probably looking for one of two things: something that stops your cashcard being taken, or something that just makes the slot look tidy and keeps the weather out. Those are different products, and in Singapore the market mostly sells the second while marketing the first.
This page prices and names every OBU cover on sale in Singapore, quotes what each seller says about their own product, and then explains what a cover cannot do — so you can decide which one you actually need before you spend anything.
An OBU cover sits over the cashcard slot. It hides the card from a glance, keeps rain and dust off it, and on some models makes the OBU look less cluttered. That is a real job, and for a car parked in a sheltered carpark it is often enough.
An OBU lock does something structurally different. It is a metal box fixed over the same slot with screws that need a power drill and extreme heat to remove, and it closes with a padlock. The card is not hidden — it is unreachable. A thief can see the card and still not get it out.
The distinction sounds pedantic until you watch how a theft actually happens: someone walks past a parked bike, lifts the card flap, and is gone in under ten seconds. A cover is lifted in that same motion. A lock has to be defeated, and nobody walking past a bike at a carpark is carrying a drill.
These are real listings, checked on 24 Oct 2026, with the material and description each seller publishes. None of them states a metal body or a lock mechanism.
| Product | Price | Material (as published) | Locks the card? | What the seller says |
|---|---|---|---|---|
| 3D-printed OBU cover (Carousell seller) | S$3.50 | 3D-printed PLA plastic | No — clip-on shell | "3D-printed using PLA material … extreme heat could cause the item to warp" |
| OBU Cover — Customised Car Mats | S$9.90 | Not stated | No — cover only | "Patented Design"; "Shield your ERP card from theft and damage" |
| Motorcycle OBU Cover — Tinkermind | S$10.00 | 3D printed in PETG | No — "open the cover first" | "adding another layer of security"; "a thief has to open the cover first" |
| OBU Cover V2 — Regina Specialties | S$15.00 | Not stated | No — cover only | "shields the card from rain, dust, and tampering"; sold out 24 Oct 2026 |
| MOTOLOCK — full stainless steel OBU lock | S$19.90 | 2mm SUS201 stainless steel | Yes — real padlock, tamper-proof screws | Card cannot be removed without a power drill and extreme heat |
The pattern is hard to miss. Four sellers, four covers, three different prices, and not one of them claims the card cannot be taken — because it can. The most honest of the four is Tinkermind, whose own page describes the cover as a layer a thief has to get past, not a barrier that stops them.
MOTOLOCK is the only product in this table with a metal body, and it is the only one where the card is inaccessible rather than concealed. It also costs S$19.90, which is S$4.90 to S$16.40 more than the covers above — for a genuinely different job, not a better version of the same one.
Most OBU covers sold in Singapore are designed for car units. LTA fits cars with a three-piece OBU that includes a separate screen, while motorcycles get a single-piece unit — different shape, different mounting, different cover. Several car-oriented listings on Carousell state it plainly: "NOTE: Not suitable for Motorcycles."
So before you buy anything described as an "OBU cover", check the listing says motorcycle. If it does not, assume it is a car cover and will not fit the unit bolted to your bike. That single check saves more money than any price comparison on this page.
Two things decide whether an accessory over your card slot actually protects anything: what it is made of, and how it is held on.
None of that makes covers useless. It makes them weather and dust protection with a concealment side effect — not theft protection. If someone wants your card, a plastic cover is a delay measured in seconds.
This is the part almost nobody thinks about. A cover exists because something underneath it is worth hiding. A thief who knows what an OBU is reads a cover as confirmation: there is a cashcard in there, and the owner was worried about it.
A plastic "lock" with a key is worse. It signals value twice — the card is there, and the owner thinks it needs locking — while opening in seconds. You have advertised the thing you were trying to protect.
Metal changes the message. A bolted steel box with a padlock does not say "there is something small and valuable in here"; it says taking it is a project. Most people will pick a different bike.
If the goal is that your card is still there when you come back, four things have to be true. Check any product against all four, cover or lock:
MOTOLOCK is built to those four points: 2mm SUS201 stainless steel, tamper-proof and chemically bonded screws, a Ø6.5mm locking hole that takes any standard padlock, and a box that closes flush over the slot. It installs on a standard Singapore motorcycle OBU without removing the unit, and the card comes out in under two seconds when you unlock it.
After a theft, most riders stop leaving money on the card. You start topping up S$10 at a time because you expect to lose it. Now you are riding to the top-up machine twice as often, running low on ERP balance at the worst moment, and still losing S$10 every time someone takes the card.
A cover does not break that loop — the card is still removable, so you still do not trust the bike. That is the tell: if you are still topping up S$10 at a time with a cover fitted, the cover did not solve your problem. A lock does, because you can top up S$120, leave the card in, and stop thinking about it. One S$19.90 lock costs less than two stolen S$10 top-ups.
An OBU cover is a plastic shell that clips or slots over the cashcard slot to hide the card from view and keep rain and dust out. An OBU lock is a metal box fixed over the same slot with tamper-proof screws and closed with a padlock, so the card cannot be removed at all. A cover changes what a thief sees. A lock changes what a thief can do. Every OBU cover sold in Singapore is made of plastic; the only full-metal OBU lock is MOTOLOCK, 2mm SUS201 stainless steel at S$19.90.
No. No OBU cover sold in Singapore has a lock mechanism or a metal body. Tinkermind's S$10 motorcycle OBU cover is described on its own product page as 3D printed in PETG and as adding "another layer of security" because "a thief has to open the cover first". Regina Specialties' S$15 OBU Cover V2 is described as shielding the card from "rain, dust, and tampering". Both are covers: they can be opened or pulled off by hand in seconds.
They are worth it for what they actually do: concealing the card from a casual glance and keeping rain and dust out of the slot. They are not worth it as theft protection. A plastic cover is held on by clips or friction and comes away with a firm pull, and Singapore's heat softens printed plastic — a PLA cover seller on Carousell warns that "extreme heat could cause the item to warp". If your goal is that the card cannot be taken, a cover does not achieve it.
Generally no. LTA fits motorcycles with a single-piece OBU, while cars get a three-piece unit with a separate screen, so the covers are different shapes. Several Singapore car-OBU cover listings state plainly that they are "not suitable for motorcycles". Check the listing says motorcycle before buying, or you will receive a cover that does not fit the unit on your bike.
OBU covers in Singapore run from about S$3.50 for a 3D-printed PLA cover on Carousell, to S$9.90 for Customised Car Mats' patented cover, S$10.00 for Tinkermind's PETG motorcycle cover, and S$15.00 for Regina Specialties' OBU Cover V2. The only full-metal OBU lock is MOTOLOCK at S$19.90 on Carousell or S$24.90 on the official Shopee store — roughly S$5 to S$16 more than a cover, for a different job.
MOTOLOCK is the only OBU lock in Singapore that is full 2mm SUS201 stainless steel, fixed with tamper-proof and chemically bonded screws, and closed with a real padlock mechanism. It is the only real lock in a market of plastic covers — and the only one where the card is unreachable rather than hidden.
It fits standard Singapore motorcycle OBU units and installs without removing the OBU from the bike. Quick release: unlock, flip, take your card in under two seconds. One-time purchase — S$19.90 on Carousell, S$24.90 on Shopee (the difference is the platform fee).
