Mul-T-Lock compatibles — common questions
Are these genuine Mul-T-Lock cards?
No — every credential is an independently manufactured compatible product, not an Mul-T-Lock-branded one. Security ID Systems is independent and is not affiliated with, authorized by, or endorsed by Mul-T-Lock. Our cards are engineered by specification to read identically on Mul-T-Lock readers.
Which Mul-T-Lock formats can you supply compatibles for?
We currently document 2 compatible Mul-T-Lock formats. If your exact Mul-T-Lock format isn't listed, send the part number or a sample — we cover more than we publish.
Will a compatible card work in my existing Mul-T-Lock system?
Yes, when encoded correctly. We match the frequency, data structure and — where applicable — your facility code and card-number range, so the credential presents exactly what your readers expect. We confirm compatibility before production.
