Question 1

Are you licensed and insured to work on Cadillac vehicles?

Accepted Answer

Yes. EZ Car Keyz holds a California Bureau of Security and Investigative Services license (LCO#6792) and carries full insurance. For a 1996 Seville specifically, the job is mechanical key cutting and resistor matching - no secure data subscriptions or factory security credentials are needed the way they are on newer platforms. That said, you still want someone who knows the PASS-Key II system well enough to check resistor values and cylinder condition, not just copy a cut and hand it back. We verify the full start cycle before we leave.

Question 2

How do I know you are not a scam locksmith?

Accepted Answer

Scam locksmiths follow a pattern. They quote a low number on the phone, then invent reasons to charge more once they are standing next to your car. With an older Cadillac, a common angle is telling the owner the vehicle has some exotic security setup that requires extra fees - when in reality a 1996 Seville needs a mechanical key, period.

A real locksmith will tell you what the job actually involves before arriving, give you a real estimate, and have a verifiable business name with reviews you can read. We have over 100,000 followers across YouTube and TikTok showing exactly how this work gets done. You can watch the process before you ever call us.

Question 3

Will the replacement key work exactly like the original?

Accepted Answer

Yes, with one thing worth knowing. The 1996 Seville's ignition reads a resistor value built into the key, not just the cut. If a replacement is made with the wrong resistor value - or no resistor at all - the car will crank and immediately cut the fuel. It mimics a mechanical problem, which confuses a lot of owners. We match both the cut and the resistor to your original so the car starts and runs normally. We test it before we leave.

Question 4

My 1996 Seville cranks but shuts off a few seconds after starting. Could it be the key?

Accepted Answer

Very likely yes. That crank-then-stall is the signature behavior of GM's PASS-Key II system rejecting the key. The ignition reads a resistance value from a small pellet in the key blade. If that value is off - worn contacts in the cylinder, a cracked pellet, or a replacement key cut without the correct resistor - the system cuts fuel a few seconds after the engine fires.

The frustrating part is it looks like a fuel or engine problem at first. Owners have replaced fuel pumps chasing this. Before you go down that road, look at your key blade. If the resistor pellet has any visible cracking, or if the symptom started right after a new key was made, that is your answer. I can decode the original, match the resistor value, and cut a replacement that the ignition actually accepts.

Question 5

Can a locksmith make a key for my 1996 Seville if I have zero keys left?

Accepted Answer

Yes. No keys at all is a standard situation. I can decode the lock cylinder directly to get the correct key cut, then match the resistor value from the cylinder's contacts. No original key needed. The whole job is done on site in Imperial Beach - no tow to the dealer, no waiting for a parts order.
