So my dad just gave me his old 2000 RX300 and he lost both of his keys which had the keyless entry buttons on it. So the only key that I have is the valet key.
How much is it going to cost to get at least one new key with the keyless entry? I called my nearest dealership and for some reason they wouldn't give me an answer, so please don't say call a professional, it didn't work. Also, the nearest dealership is 3 hours away, so if its going to cost me an arm and a leg I don't want to make the trip.
Please & Thank You!

 

Try Ebay. You will need to get instructions to program the electronics to work with your car and get a blank key (also on Ebay) which will have to be cut by a dealer or locksmith. Probably looking at a hundred to a hundred and a quarter total.

 

i got mine for around $200 from dealer.

 

It is a bit complicated.

First it seems, that the master key is lost. Master key is needed to program duplicates to be registered with the ecu. That means a new ecu along with new keys OR have having the ecu reflashed [I doubt that a dealer would do this]

I would say call the dealer again and talk to a service agent or service manager and explain your situation again.

Call well known locksmiths and see if they can handle Lexus.
