Hello! I recently got around to having a 2nd transponder key made for my 2013 Honda CRV EX-L to replace one that went missing a few years ago. Because I was trying to save money, I decided to buy a blank transponder key on Amazon ($15), program it myself ($ Free) and have it cut at Batteries Plus ($20).

The key looks like this - https://www.amazon.com/Replacement-...cphy=9010927&hvtargid=pla-1153364605569&psc=1

I followed this method for programming, which worked fine -

The new key remote works fine to lock and unlock the car, but when I try to start the car with it, the green key immobilizer light continuously flashes and the engine will immediately turn off after starting. I have tried reprogramming the keys a couple of times now and I'm still having the same problem.

Does anyone have any experience with this? Any help would be greatly appreciated! Thanks!

You need a bidirectional scanner with a function for programming the immobilizer to accept the key. Car shops and some locksmiths can do this.

Programming the FOB and programming the ignition key are two different things. The FOB you can do but the immobilizer must be done by a specialist with the proper programmer. Both items are in the key head but are completely different.

Yes, programming the key fob to work the keyless entry is easy enough
And can be done by the owner without special tools.
However, if you want to program the vehicle to accept the new key to run the engine
Then the new key must have a transponder for the immobilizer unit
And it must be done with a scanner with the ability to program the immobilizer/ECM
Those scanners are not cheap. But, they can be found for sale on the internet.
If you find a cheaper method then please let us know.
