I bought my Spyder with only one key. Several years ago I misplaced my key, found it again a day later. Wow, just lucky. I did not panic as the Spyder is not my only car, but the next day I located a local Locksmith who special ordered a clone Toyota key, cut it and programmed it for free. It was not cheap. Took about a week. Now I have two Master Keys. I also had them make a copy of the Remote. I use both copies and keep the originals locked away. Yep, good warning.

You can buy key blanks and get them cut and program them yourself. I just ordered a flip out key after reading about it on some other threads on here. ~$40 for the key and $2 to get it cut in town and programmed it myself. I will say the key wasn't perfect haven't gotten it to work in my cubbies or glovebox yet, have been doing some filing on it. It works fine in ignition and doors though.

My spare key cost me $17 total. The lady at home depot even cut it for free & told me good luck programming it lol.

A working spare can be bought off eBay for <$20. Pay to have it cut, then program it with the key dance. At that price you're crazy not to have a spare key handy.

It is worth it to get a spare, whatever it costs. The chip is the key to the immobilizer. An existing key can be cloned without too much trouble, but no keys at all is a big problem. You either need a new ECU, or you have to get the existing one wiped by someone who knows how to do it.

These guys will clone your key into a flip key for 50$: Toyota MR2 Spyder Flip Blade Key

As you have said most things have moved to the internet - blanks are pretty cheap online and then you can have them cut locally. If your key is a master key there are instructions somewhere on the forums on how you can add the key to your immobilizer but I have not done that myself.

Here is the “pedal dance” process (below) to program an additional chipped key to your car. You must have a master key for this to work (a valet key will not suffice). Order a key from Amazon or eBay. I paid $12 for two of them. Have the hardware store cut them to match your master key. Then go home and do the pedal dance.
If you only have a valet key, or no keys at all, I can send you the process to clear the immobilizer. After which the ecu will accept any three keys you choose to program. The process is a little more involved but only requires $75 worth of eprom programming bits.

Get in the car and shut the doors
press and release the brake and gas pedal once
insert your master key into the ignition switch
press and release the gas pedal 5 times
press and release the brake pedal 6 times
remove master key
insert new key
press and release the brake and gas pedal once
wait 80 seconds
remove new key
press brake

IF YOU ALREADY HAVE A MASTER KEY:
Making a spare key is cheap and easy. You buy the blank (with transponder chip) on eBay. It is an Ilco brand key. You have any locksmith cut the blank. Then you program the new key to the ECU using either the "PEDAL DANCE" (search for this) or TECHSTREAM (search for this).

IF YOU DO NOT HAVE A MASTER KEY:
You have a few options, none so simple.
1. You reflash the immobilizer chip on the ECU motherboard (search for how to do this)
2. You buy an ECU with a paired master key, and then you go back to "IF YOU ALREADY HAVE A MASTER KEY" above.
3. Some people just buy a JDM ECU no immobilizer - but this has its own set of problems.

I have made some videos showing how to program a spare key.

Here is another write up of the “pedal dance” procedure. I have not personally done either one.

To register an additional master key:
· Insert already registered master key into key cylinder
· (within 15 sec) Depress and release the acceleration pedal 5 times.
· (within 20 sec) Depress and release the brake pedal 6 times then remove the master key.
· (within 10 sec) Insert key to be registered as a master key into the key cylinder.
· (within 10 sec) Depress and release the accelerator pedal 1 time (security light blinks).
· Wait 60 seconds and the security light will go off and the new key is now registered.
· Remove key and press and release brake once within 10 seconds of security light going out to end the program mode.
· Program mode will also end 10 seconds after (either the security light going off or removing the key).

I believe I used this procedure with the exception of making sure the doors were shut like your first procedure mentions.

I need to get a spare but have a kswap with Hondata ecu. Is the process the same?
With a k-swap and most other swaps you have no immobilizer. You can have an ordinary key (no transponder chip) made by copying the existing key, or for a factory-spec key, use the numeric key code that is embossed on the passenger side lock cylinder (inside the door - yes this requires disassembling the door). No need to program the key to the ECU.

Thanks for this. You or anyone know if the non-transponder oem keys work/same size? I assume e.g. an sw20 oem blank can be cut to work?

If you only have a valet key, could you not just clone it?

You can't program a new key to the car with the 'pedal dance' unless you use a master key to do it.

Understood.. but if you have a valet key pretty sure you can take it without the car to any locksmith and have it cloned

I suppose..but if you only need a valet key then you have a master key & really just want another master key. Biased personal opinion but honestly I don't see the point of a valet key in these cars at all...even new they were only an intro level sports car.

Locksmiths are "supposed" to verify proof of ownership so without the car & with the registration + photo ID they should be able to do it. I thought there was a separate pedal dance to program valet keys as well.

I believe that the valet key is copy protected. The mechanical code can be copied, but the electronic code cannot. That would make sense. The valet key has a mechanical code that does not access the storage areas, but it is the electronic code that prevents someone from stealing the car.
