Problem with starting and code 1648 in a Chevrolet Spark

Hello, I have a 2010 Chevrolet Spark with 190,000 km and I'm having trouble starting the car. For a month now, the car starts whenever it wants. Initially it did it rarely, but now it has become more frequent. For example, in the morning it starts normally, but if I turn it off and try again after half an hour, it won't start. After many attempts, it finally starts. The diagnostic check showed the code 1648, which indicates a problem with the immobilizer. Replacing or removing the immobilizer is very expensive. What other solutions do you suggest? After 1-2 hours it starts again.

Summary of the thread

A 2010 Chevrolet Spark with 190,000 km is experiencing intermittent starting issues, with a diagnostic code 1648 indicating an immobilizer problem. The car starts normally in the morning but struggles to start after being turned off for a short period. Replacing or removing the immobilizer is costly, so alternative solutions are sought. One suggestion is to check and clean battery connections and test the battery to ensure it holds a charge properly.

Check the battery connections and ensure they are clean and tight. A weak or poor connection can cause intermittent starting issues. If the connections are fine, consider having the battery tested to ensure it’s holding a charge properly. Let me know how it goes or if you have any further questions!
