Steel-Line, Boss and Guardian Garage Remote Compatibility Guide
Quick answer: Steel-Line, Boss and Guardian products span multiple remote families. Match the exact remote and opener codes, then confirm frequency and coding generation.
Buying a replacement remote is much easier when you match the technical identifiers first and the appearance second. This guide explains what to check before ordering from The Remote Factory.
Steel-Line ZT-07 family
ZT-07-compatible products are commonly listed for selected Steel-Line openers such as SD800, SD1200 or SPRINT800. Check the motor label and original remote code because Steel-Line has used other transmitter systems that are not covered by a ZT-07 listing.
Boss and Guardian BHT4 or 2211-L family
Boss and Guardian compatible listings can reference BHT4, HT4, 2211-L, 2211-L (TX), BOL4, BOL6, BOL9, BRD1, BRD3 or BRD9. The product page should identify exactly which codes and generations are supported.
Watch for older DIP-switch remotes
Some older systems use internal DIP switches, while newer compatible remotes can use a learning or rolling-code method. A replacement may explicitly exclude older DIP-switch models even when the casing or brand looks similar. Open the old battery cover and inspect the code where safe.
Do not rely on the brand logo
Garage motors and transmitters may be sold under related or distributor brands, and a compatible aftermarket remote may not carry the same branding. Model and coding information is more useful than the logo when checking technical compatibility.
Compatibility checklist
- Original remote model matches the listing.
- Opener or receiver model is supported.
- Frequency matches.
- DIP-switch or rolling-code generation matches.
- Programming method matches the product instructions.
- Excluded models have been reviewed.
When you have no working remote
Use the motor and receiver labels rather than guessing from an online image. If the existing radio system cannot be identified or the transmitter is obsolete, ask a garage-door technician whether a receiver upgrade kit is suitable.

Frequently asked questions
Does every Steel-Line opener use ZT-07?
No. Confirm the opener and original remote model.
Are 2211-L and BHT4 listings always compatible with old DIP-switch remotes?
No. Some listings exclude older DIP-switch generations, so inspect the original and read the exclusions.
Can the same compatible remote be listed under Boss, Guardian and Steel-Line?
Sometimes related model families overlap, but compatibility must be confirmed by the exact codes in the listing.
Still unsure? Start with the complete remote-control catalogue and compare the model number, button layout and compatibility notes before placing your order.
