Detailed Answer
Sources of price differences: 1. Number of keys/features (6-key entry vs 12-key flagship); 2. Protection rating (IP65 vs IP68); 3. Safety features (basic vs RFID/bidirectional); 4. Brand (domestic vs import); 5. Certification (standard vs explosion-proof); 6. Service (warranty/trade-in). LDER ¥268–¥978 (value), XINGJIA ¥350–¥1,800 (full product range), import ¥3,000+. Choose based on needs — buy what's right, not what's expensive.
