Excerpt: Rolling code remotes are higher-priced and more secure. Fixed code remotes are universal and cheap. The wholesale buyer’s decision tree for which to stock, and how to carry both without bloating inventory.
Introduction
The fixed vs rolling code decision is the second-most-asked question in B2B RF distribution (after frequency). It’s also one where suppliers frequently misrepresent their products. Here’s the wholesale decision framework.
The technical difference, briefly
Fixed code remotes send the same digital number every press. The receiver has a list of acceptable numbers; if your remote’s number is on the list, the door opens. Simple, cheap, but vulnerable to code-grabbing attacks. Rolling code remotes send a different encrypted number every press, with the receiver and remote both running the same algorithm. The receiver accepts any number that follows the previous valid one in the sequence. More secure, more complex, more expensive.
When fixed code is the right answer
Industrial and commercial applications (factories, gate motors for warehouses, agricultural pumps) often use fixed code because the security risk is lower and the cost matters more. Fixed code is also the right answer for distributors serving the global ‘multi-frequency cloner’ market — these devices learn from an existing fixed-code remote and replay it.
When rolling code is required
Residential garage doors in the US, EU, and ANZ markets are predominantly rolling code. If your customer is a residential installer or a homeowner replacement market, you need rolling code remotes. Hörmann BiSecur, Merlin Security+, Chamberlain Security+ 2.0, Nice FloR, and SOMMER are all rolling code families.
MOQ strategy for both
Don’t choose — carry both, but tier your MOQ. Fixed code cloners: MOQ 500 pcs at 4-band. Rolling code remotes: MOQ 500 pcs per brand-protocol pair. The total catalog volume is higher, but you can rotate slow-moving SKUs to the sample-kit tier (100 pcs) without losing the OEM discount structure.
The bottom line
If you can only afford one line, carry rolling code — it’s where the residential and premium-commercial markets are migrating. If you can afford two lines, pair rolling code for residential with a fixed code cloner for the industrial / multi-brand replacement market. Most successful distributors run 60-70% rolling code SKUs and 30-40% fixed code.
