Secure your home or office with TCL smart locks, including the D2 Pro Palm Vein Door Lock and D2 Plus Fingerprint Door Lock. Follow this step-by-step guide to rekey your smart lock efficiently and safely.

A smart lock is a modern security device that grants access without traditional keys. Instead, it uses:

• Biometric recognition: Fingerprint or palm vein scans

• PIN codes or keypads

• NFC or RFID cards

• Smartphone app control

Benefits of TCL Smart Locks:

• Keyless entry for convenience

• Remote monitoring via smartphone

• High-precision biometric authentication

• Audit trails to track entries

Even advanced smart locks require occasional rekeying to maintain security:

• Lost or stolen credentials

• Moving into a new property

• Security upgrades

• Routine maintenance

Rekeying ensures that only authorized users can access your home or office.
