DOORKING Product Lines We Repair
Our engineers are trained on the full DOORKING product range. Below are the major product families we service.
DoorKing 6000 Series Gate Operators
Heavy-duty sliding and swing gate operators with AC/DC motor options. Common issues include motor burnout, limit switch failures, control board processor errors, and solenoid coil degradation due to heat and humidity in Indian industrial environments.
DoorKing 2600 Series Access Control
Integrated access control with card readers, keypad entry, and relay outputs. Typical faults include card reader communication failure, firmware corruption, power supply voltage sag, and gate communication protocol timeouts in multi-unit installations.
DoorKing Loop Detector and Sensor Systems
Inductive loop detectors for vehicle detection and safety activation. Common failures include loop coil breaks, detector board noise interference, low sensitivity calibration drift, and water ingress in outdoor parking and industrial gate applications.
DoorKing Power Supply Modules
Regulated 12VDC and 24VDC backup power units with battery backup and surge protection. Repair issues include transformer secondary winding shorts, regulator IC failure, battery charging circuit malfunction, and thermal overload under continuous duty cycles.
DoorKing Wireless Remote Control Systems
2.4GHz and 315MHz radio transmitter/receiver modules for gate activation. Faults include receiver crystal oscillator drift, RF module demodulation failure, code synchronization loss, and interference from industrial machinery and telecom infrastructure.

Common DOORKING Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DOORKING equipment arriving at our workshop.
- ✓DoorKing Gate Operator Motor Stalled or No Movement — DC motor winding failure due to thermal stress from high ambient temperature and continuous operation in Indian climates, or mechanical jam in gate track. Limit switches may also be malfunctioning, preventing motor contactor release.
- ✓Access Control Card Reader Not Reading Cards — DoorKing 2600 series reader IC failure, corrupted EEPROM firmware storing card codes, or poor magnetic coupling due to dust and salt spray in coastal Indian industrial zones. Cable connection corrosion at reader port can also disable communication.
- ✓Loop Detector Sensitivity Loss or False Triggering — DoorKing 2200 series loop coil wire break under repeated stress cycles, capacitor drift in resonant circuit, or RF interference from adjacent industrial machinery, power lines, and mobile towers common in manufacturing clusters.
- ✓DoorKing Control Board Processor Watchdog Reset or Halts — Firmware corruption from power interruption, defective crystal oscillator providing unstable clock timing, or memory address corruption from electrostatic discharge during humid Indian monsoon seasons.
- ✓Power Supply Backup Battery Not Charging — DoorKing PS-3 charging circuit regulator failure, battery terminal corrosion preventing DC current flow, or defective diode blocking reverse current in the charging path.
- ✓Wireless Remote Control Transmitter Not Activating Gate — DoorKing 8072 receiver crystal oscillator aging causing frequency drift beyond receiver lock-in range, receiver demodulator IC failure, or code synchronization loss if remote power cell voltage drops below 2.5V.

Frequently Asked Questions — DOORKING Repairs
Do you repair DoorKing gate operators and access control systems across India?+
Yes. Synchronics Electronics repairs the complete DoorKing product portfolio — gate operators (6000 series), access control modules (2600 series), loop detectors, power supplies, and wireless remote systems. We offer nationwide pick-up from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, Surat, Vadodara, and all major industrial cities. All repairs are completed at our Vadodara facility with 48-72 hour turnaround for most faults.
What is the typical repair cost for a DoorKing 6000 series motor operator?+
DoorKing gate operator repair costs range from Rs. 8,000 to Rs. 25,000 depending on fault type. Motor rewind or replacement adds Rs. 12,000-18,000. Limit switch replacement and control board testing is included in base service charge. Synchronics provides free diagnostic analysis and quotes before commencing repair, with no charges if equipment is deemed unrepairable.
Can DoorKing 2600 access control firmware be reprogrammed if corrupted?+
Yes, absolutely. Synchronics stocks DoorKing 2600 firmware ROM images and can reflash corrupted EEPROM within 24 hours. We also restore your original card database if stored. However, if the flash memory IC itself is physically damaged (shorted pins or burned die), the control board must be replaced. We carry DoorKing OEM and compatible replacement boards in stock.
How do I know if my DoorKing loop detector coil is broken?+
A broken loop coil will show zero ohm resistance or open circuit when measured with a multimeter. DoorKing 2200 loop detectors may also display false triggers or no vehicle detection even with cars present. Synchronics uses a loop resistance analyzer to diagnose break location and recommend repair. If the coil is in the road surface, we provide guidance on safe surface excavation and coil replacement.
Does Synchronics stock DoorKing spare parts and replacement components?+
Yes. Synchronics maintains inventory of DoorKing motors, power supplies, reader modules, loop detector boards, remote receiver units, and control board components. Lead times are typically 5-7 days for OEM parts from our authorized distributors. For urgent repairs in Indian plants, we often have compatible alternatives in stock. Contact our Vadodara facility for parts availability and pricing.
How do I send my DOORKING unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a DOORKING drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on DOORKING repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your DOORKING unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
