Yeah just try any of the BT options, assuming you have a smartphone. They're affordable and easy to carry with you. Keep a dongle in each vehicle. I've been using a Veepeak?? I got on a warehouse deal for something like $8
Real scumbags will buy these, use Carista to turn off Toy seat belt chimes, then return the dongle.
Whatever you're looking at, weigh cost and/or subscription against risk. ie if it's a free app and you hate it, you just uninstall. If it's ~$10, probably low risk and worst case you're out $10 if you hate it. You'll have to decide where your threshold is for "too expensive"
Some apps like Jscan are good for CDJR. But if you want to do advanced things you need to pay for a $25 license and it's good for that vehicle only. However it can be well worth it, depending upon what you're doing. Also if you hit that point in Jscan and don't want to pay, you certainly don't have to. Just look for other solutions.
Finally, keep your eyes peeled for old Snappy bricks or Modii -- they're some of the very few that can pull 2nd Gen ABS codes, and these vehicles LOVE to illuminate that ABS light. In '96 you just get a weird two-digit code I think, but you can't get that from the key dance AFAIK
