💡 How do you write unencrypted 125kHz blank T5577 tags for a facility upgrade?

This handy setup lets you mass-produce credentials without waiting for vendors. You just need a writer that matches the low-frequency band and a quick compatibility check.

• Choose a dedicated 125kHz programmer device to burn your specific IDs onto the raw T5577 chips.
• Confirm your existing locks accept unencrypted signals at this frequency so the new tags pair correctly.
• Avoid relying on smartphone NFC features since those tools operate on a different high-frequency band.
• Keep these tags away from Onity installations because those doors demand proprietary encryption and won't accept generics.
