This is the remote control for the Daihatsu Thor's remote engine starter. I am selling it due to the sale of the vehicle. I used it for 3 years, but the frequency of use was quite low. I think I only used it about 50 times. It powers on. It can still be used without any problems. Please re-register it at the dealer for use. I do not know if it can be used for Toyota Roomy, Tank, or other Daihatsu models, so please refrain from asking questions about compatibility. Instant purchase welcome Remote starter with engine start/stop function, equipped with LED indicator. - Model: Remote Starter - Battery type: 2 x CR2032 - Operation: Engine start/stop - Display: LED indicator Thank you for viewing.
