Honda Activa — activa

Address: Dehradun, Uttarakhand, 248001

My new honda activa 4g from ess ell honda dehradun was opened with keys from activa 3g from hrishikesh and vice versa. When we complained in the showroom they informed that they make keys from number 1 to 999 and then the sequence returns. This means that in dehradun if there are 1 lac activa with one key we can open 100 activa in dehradun itself. Is this correct? Or are the employees in ess ell honda saying a lie. I also asked in their workshop and they gave the same answer.
