Smart Access: The i-Car i-Door Proximity Module
Imagine your Kia Carnival KA4's doors automatically unlocking as you approach and locking as you walk away, all without touching your smart key. This is the convenience offered by the i-Car i-Door proximity door module, a popular factory option retrofit for the KA4 Carnival. Beyond the core auto-open/lock feature, this module enhances your driving experience with several smart functions. If you don't have your smart key handy, you can still unlock the doors by entering a pre-set password on the door handle touch button. It also includes an intelligent auto-close window function – if you lock the doors with the windows open, they'll automatically shut. For added safety, a rear-flash function for the hazard lights during reversing can be toggled on or off.
Installation Process for Your Kia Carnival KA4
The installation of the i-Car i-Door module involves precise wiring work by a professional technician. Following the wiring, a thorough test ensures all functions operate correctly.

The quality of the wiring and the meticulous application of sound-absorbing tape are crucial for preventing future issues like loose wires or unwanted noises.
