The Remote Warehouse has a range of Guardian remotes for garage doors. If you are confused by the fact that your remote may be labelled Guardian, Steel Line or Boss please don't be, these remotes are fully compatible and are the same items branded for different markets. All remotes in this collection suit garage opener models 21230, 21230L and 2211-L. These units are especially easy to program having only a three step programming sequence, the programming instructions are included with every parcel. We stock Genuine Guardian remotes and also have high quality aftermarket replacement remotes available. If you wish to keep your remote on your sun visor we recommend buying the genuine Guardian remote, as the sun visor clip is included. If you wish to keep the remote on your keyring we recommend one of our high quality aftermarket remotes, as they are of a smaller size. Our one button aftermarket remote is ideal for operating just the one Guardian garage door opener.
