Three hex numbers are noteworthy for the key_code (key_code) and the key_count (key_count) and the V_ARG_ENABLED. To "virginize", the chip, change all other hex values from the number 00.

If the sensor detects this, the car will unlock itself and may switch on the interior lights if it is set up to do so.
Even older keyless entry systems come with an old-fashioned backup. If the remote doesn't work it is still possible to manually open the driver's door.
