Verdict
The clearest difference is in-app purchases: Ert Replace at none against Car Key Connect's 6. Ert Replace also leads on ads (none vs shown) and rating (5.0 vs 4.7). Car Key Connect's advantage is ratings volume (27K vs 1) and chart position (#82 vs unranked). On price, update cadence and iOS requirement there is nothing between them.
