Versatile 4‑Button Cloning Remote — 433MHz RF, Keychain Size Why you need this or duplicate original factory remotes for vehicle central locking systems and electronic garage doors quickly and affordably. Carry a compact backup on your keychain for immediate access when the original remote is lost, damaged, or left at home. Strong RF signal that can pass walls and floors for reliable operation through typical household and garage barriers. Key benefits Multibutton flexibility: Four independent buttons allow cloning of up to four functions or devices on a single remote. Unlimited reprogramming: Reset and re‑set buttons as needed; no fixed limitation on programming attempts. Portable and durable: Compact keychain design built from sturdy materials for everyday carry and longlasting use. Strong performance: 433MHz RF transmission (433.92MHz typical) provides robust range and penetration. Compatibility (encoder chip models supported) 2260, 2262 (such as PT2262, SC2262, HS2262, LX2262, HX2262, etc.), 1527 (EV1527, HS1527, HX1527, SC1527, GP1527, CP1527, AD1527, SCL1527, TL1527, ZX1527), PT2264, PT2240 (LX2240, LX2241, SCL2240), CS5211, SMC918, AX5026, SMC926, AX53263, AX53264, FP527, HT600, HT680, HT6207, HT6010, HT6012, HT6013, HT6014, HT12D, HT46F49E, PIC16F630, ULN2003. Note: Different chip manufacturers may use different model prefixes; compatibility depends on matching the chip model numbers listed above. Important pre checklist Confirm the original remote currently works normally. Confirm the original remote frequency is 433.92Mhz. Confirm the original remote uses one of the encoder chip models listed under Compatibility.
