Is it reasonable to charge for property access card in 50 yuan?

It depends on the price given by the access card production company to the property management company.

As far as I know, some access card companies require a 50 yuan card when they sell properties, although this card does not exceed 10 yuan in the computer city.

At present, the state has no regulations on this market. The access control system is integrated. If the manufacturer's access card is not used, the manufacturer will refuse the warranty of the access control system on this ground. So sometimes the property can't help it.
