A new flip/smart key shell in a modern style for Toyota vehicles – the perfect solution for refreshing and replacing a worn-out or outdated key fob. Designed to replace an old key by transferring the electronic internals (transponder, chip, circuit board, and battery) from the original key into this new stylish housing. This way, you get a visually new key while retaining all the functionality of the old one, including the immobilizer and remote control system.
Key features of the Toyota key shell ATT4:
- Modern Design: Ergonomic and stylish flip/smart key housing with three buttons for basic functions (lock/unlock, open trunk, panic).
- Direct Compatibility: Designed to replace the housing of keys for many Toyota models. All electronic 'guts' from your old key are installed into this new shell.
- Full Kit: The kit includes the Toyota brand logo for installation on the housing, giving the key a finished and quality look.
- Shell Only: Supplied without electronic parts (chip, board, battery). This is a housing for self-transplanting your internal components.
- Product Code: ATT4
- Build Quality: The housing is made of quality materials providing pleasant tactile sensations and durability. Buttons have a clear press, and the key blade ejection mechanism works smoothly and reliably.
Replacement Process (briefly): To replace the shell, you will need to carefully disassemble the old key, extract the electronic module with the chip and battery, and transfer it to the new ATT4 housing. After assembly, the key is ready for use. If you are unsure of your skills, we recommend contacting a key-making specialist or a car service.
