What is the Difference Between a Regular Car Remote Key and a Smart Remote Key?

[LouisAnn]

Car regular remote keys and smart remote keys differ in functionality. Regular remote keys can only lock/unlock doors and activate the anti-theft alarm, while smart keys, in addition to these functions, can also disable the engine control unit (ECU) chip, providing a higher level of anti-theft protection. Smart remote keys utilize radio frequency technology and vehicle identification coding systems, integrating both remote control and keyless entry systems to achieve a dual RF system and dual anti-theft protection, offering maximum convenience and security for car owners. The types of car keys include: mechanical keys, remote keys, touchscreen LCD keys, and smart wristband keys. Precautions for using car keys: Do not place them near electronic devices, avoid exposing them to direct high temperatures, do not use batteries with different power levels, and pay attention to daily protection. Method for replacing car key batteries: Remove the car key, insert a flat-head screwdriver into the side gap to open the key cover, and then replace the battery.
