Before Attempting a DIY Car Key Repair

Car key repairs vary in difficulty. Some repairs involve transferring components into a replacement case, while others can require the key to be opened, dismantled or soldered. Only attempt a repair if you are confident that you have the appropriate tools and skills.

Care should be taken when working on a remote key because damage to the circuit board, transponder or other internal components can prevent the remote or vehicle key from functioning correctly. Please check the individual product description before starting your repair.

Prefer Us to Repair Your Key?

If you would rather not carry out the repair yourself, we also offer a professional car key repair service for many vehicle keys. Depending on the fault, we can replace damaged cases, batteries, micro switches and other components before professionally testing the key and returning it to you.

Repair & Refurbish Your Existing Vauxhall Zafira C Tourer Key This kit provides the commonly required components for refurbishing a worn or faulty remote key while retaining your original programmed electronics and transponder. Depending on the condition of your existing key, the kit can be used to address: Worn, cracked or damaged key cases Worn or non-responsive buttons Faulty button micro switches Weak or flat CR2032 batteries Worn or damaged flip-key housings A new battery or replacement case will not repair unrelated circuit-board faults. If the original key has an electronic fault, further diagnosis or professional repair may be required.

If your original blade is suitable for reuse, the supplied tool can assist with removing the small retaining pin so that the original blade can be transferred into the replacement flip-key mechanism. Alternatively, the supplied uncut HU100 blade can be professionally cut to match your vehicle. Step-by-Step Video Fitting Guide Included Every kit includes a QR fitting-guide card in your parcel. Simply scan the QR code on the card with your phone to access our detailed step-by-step fitting tutorial on YouTube.

Please keep the fitting-guide card until you have completed the repair. CR2032 Replacement Battery The kit includes a new CR2032 3V lithium coin-cell battery for the compatible remote key shown. Fit the replacement battery in the correct orientation, matching the polarity of the original battery and the markings inside the key or battery holder. Replacement Micro Switches The kit includes two 4-pin replacement micro switches for compatible circuit boards. The switches are intended for keys with worn, damaged or non-responsive button switches. If the existing micro switches are working correctly, they do not need to be replaced simply because replacements are supplied with the kit. Replacing micro switches requires soldering skills and suitable equipment. Excessive heat, incorrect fitting or damage to the circuit board can prevent the remote key from functioning correctly.
