Replace a keyboard?

My Novatech Elite N1768 is about 3 years old and the V key is failing intermittently. Is there anything I can do and if not can i change my keyboard and at what cost?

if the silicone from under the keys is not damaged, you can change it without problems and very cheaply, otherwise you will have to change the keyboard
and from the new keyboard models I can advise:
SteelSeries Apex 3 (80 $)
Corsair K95 RGB Platinum (140 $)
SteelSeries Apex 7 (160 $)
all keyboards are mechanical and with cable
