Customer: Jinan

Project Scope: Chip Decryption, PCB Cloning, BOM Generation, Prototype Assembly, and Debugging

Project Highlight: Decryption of Rolling Code Chip HCS300

When we received the customer's product, it was quite simple - just two remote controllers used in cars. Our engineers immediately recognized that it was a car anti-theft alarm system and mentioned that it contained a rolling code chip, which we could handle. We promptly informed the customer, and their immediate response emphasized their trust in our professionalism. The customer sent us the receiver, a small iron box.

Now, let's introduce some information about the rolling code chip. The rolling code decoding chip is developed for wireless remote control security systems. It addresses the drawbacks of fixed-code chips, which have low encoding volume, are highly susceptible to code repetition, and have easily scannable and decipherable data. Common encoding ICs include PT2272, AX5327, VD5027, etc.

Based on the above information, we know that rolling code chips are mainly used in car anti-theft systems, car and motorcycle alarms, home access and garage doors, car electronic locks, identity recognition, and anti-theft remote control systems.

Rolling code chips ensure non-repeating, random codes, and in essence, they are designed for secrecy and security. They generally involve higher levels of difficulty. Dongdao Technology in Shenzhen can undoubtedly claim to be at the forefront of the industry in terms of rolling code chip decryption. We have encountered cases where clients approached other companies first but were unsuccessful until they turned to us for assistance.
