Dell Latitude e6230 keyboard - where to buy?

I have a perfectly working Dell Latitude E6320 laptop from ages (i5, 8gb ram, 256gb SSD). It is much better some of the newer laptops.

But it’s keyboard has stopped working – some keys are not functioning. I guess it’s best to replace it’s keyboard again.

Prices of these keyboards are usually ₹600-800. Amazon & FK are listing them for 1k-2k.

What is the best way to get a replacement keyboard without shelling out tons of money to Amazon / FK? (Any reco online shops from nehru place or lamington road)..
