Dear All,
Thx all for your feedback. I have checked the car with reputed organization. No issues with the vehicle. That is good enough for me.
Seems like these guys have swapped the duplicate key with another car. Also car was registered in Japan in 09/2017. Shipped to Sri Lankan 10/2017 (Milage 27). stayed in sale for 3-4 months. No words for their unprofessional and rude customer service. Anyway they are not thinking about customers returning back to them anyway.
On down side I have to get a duplicate key from Key Lanka for 16500/=. I have decided to avoid 2nd and 3rd labor free services from them. Well about warranty it covers few things that are highly unlikely to fail in Toyota. Make sense for me to do proper service for long run.
I guess we can conclude the discussion.
