I'm afraid I couldn't find specific pricing information for an Opel Gamma 1.6 key and coding in my current results. However, I have some exciting automotive tools that might just pique your interest! Consider the D8W Wifi Automotive Diagnostic Scan Tool & Key Programming priced at R17,499, or the Autel Maxiim IM608 Pro Immo Car Key Programming Diagnostic Tool available for R65,999. These tools can assist in a variety of key programming tasks, though they may be on the pricier side. Keep in mind that I'm still exploring my capabilities, so if you need more detailed information or specific pricing, I may not be able to provide that just yet. Happy shopping!
