Key Cards Compatible With Your Hotel Lock System
Almost every key card problem traces back to one question: does the chip match the lock? This page explains how to answer it before you place an order.
- Frequencies
- 125 kHz and 13.56 MHz
- Verification
- Send one sample card
- Validation
- Test batch before full run
- Delivery
- Encoded and sequenced
Step one: identify the frequency
Most installed hotel locks read 13.56 MHz credentials. Older installations may still use 125 kHz proximity cards. If you do not know which you have, send us a sample card — we identify frequency and chip family from it.
Step two: match the chip family
Within 13.56 MHz there are several families with different memory and security models. Encrypted families are used where the lock writes stay data to the card; simpler families suit systems that only read a serial number.
Your lock supplier's specification is the authority here. We produce to that specification rather than guessing from the lock brand alone.
Step three: encoding and validation
We encode cards to your specification, sequence them, and send a validation batch to test on your own doors before the full run ships.
Frequently asked questions
+Can you replace our current key cards without changing locks?
Yes. We match the chip and encoding of your existing card so the new cards work on the installed locks.
+What do you need from us to confirm compatibility?
One sample card, and ideally the lock system specification from your supplier.
