How to register a new key
To register an additional key yourself, you need a master key (black).
For some models, the sequence of operations according to AUTODATA is suitable.
In most cases, such operations do not bring results. On the Internet you can find many sequences of “shamanic” operations such as turn the ignition on and off five times, turn on the ignition, then open and close the driver’s door seven times, turn off the ignition, insert a new key, and after 40 seconds it will lock itself. Official dealers do not confirm such information (though they do not refute it). Of course, there are special means of surgical intervention, but their dealers keep them secret, this is their bread.
The most reliable way to bind keys is to use special equipment. The most optimized and inexpensive equipment is Toyota Smart 4C&4D Keymaker OBD2 or its more advanced versions.
With its help, you can register additional keys using the following algorithm:
- The equipment is connected to the car via the OBD diagnostic connector.
- The ignition is turned on, the connection is confirmed by a “beep” sound signal.
- Press the “Start” button twice. After connecting the smart device to the car and reading the key code, a multiple beep will sound, after which the ignition should be turned off.
- Remove the main key.
- Insert new key. Turn off the ignition.
- After connecting to the car (multiple beeps), the key is paired. Upon completion of the binding, the ignition must be turned off and on five times.
The procedure for binding smart keys occurs automatically when the device is connected to the OBD diagnostic connector of the car. For different models of key programmers, there may be certain differences in the sequence of operations described in the attached instructions.
The cost of Toyota Smart Keymaker on Chinese sites is from 500 rubles. It's cheaper than tying up one key at a service station.
